Introduction

Matilde wants to build a wooden planter in the shape of a right triangle for their garden. One side will be formed by an existing bench that is 96 inches long. To fence the other two sides, Matilde wants to use pieces of wood that are each precut to 12 inches. In this article, we will explore the mathematical concepts involved in building this planter and provide a step-by-step guide on how to achieve it.

Understanding the Problem

To build a right triangle planter, we need to determine the length of the other two sides. Since one side is already formed by the existing bench, we can use the Pythagorean theorem to find the length of the other two sides. The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

The Pythagorean Theorem

The Pythagorean theorem can be expressed mathematically as:

a^2 + b^2 = c^2

where a and b are the lengths of the two sides that form the right angle, and c is the length of the hypotenuse.

Applying the Pythagorean Theorem

In this case, we know that one side of the planter is 96 inches long, and we want to use pieces of wood that are each precut to 12 inches. We can use the Pythagorean theorem to find the length of the other two sides.

Let's assume that the 96-inch side is one of the sides that form the right angle. We can call this side "a". Since we want to use pieces of wood that are each precut to 12 inches, we can call the other side "b". The hypotenuse of the triangle is the side that is opposite the right angle, and we can call this side "c".

We know that the length of side "a" is 96 inches, and we want to find the length of side "b". We can use the Pythagorean theorem to solve for "b".

Solving for Side "b"

Using the Pythagorean theorem, we can write:

a^2 + b^2 = c^2

Substituting the values we know, we get:

96^2 + b^2 = c^2

Expanding the equation, we get:

9216 + b^2 = c^2

We also know that the length of side "b" is 12 inches. We can substitute this value into the equation:

9216 + 12^2 = c^2

Simplifying the equation, we get:

9216 + 144 = c^2

Combine like terms:

9360 = c^2

Now, we can take the square root of both sides to solve for "c":

c = √9360

c ≈ 97.0

Now that we have the length of the hypotenuse, we can use it to find the length of side "b".

Solving for Side "b" (continued)

Using the Pythagorean theorem, we can write:

a^2 + b^2 = c^2

Substituting the values we know, we get:

96^2 + b^2 = 97^2

Expanding the equation, we get:

9216 + b^2 = 9409

Subtracting 9216 from both sides, we get:

b^2 = 193

Taking the square root of both sides, we get:

b ≈ 13.9

Conclusion

In this article, we explored the mathematical concepts involved in building a wooden planter in the shape of a right triangle. We used the Pythagorean theorem to find the length of the other two sides, and we provided a step-by-step guide on how to achieve it. By following these steps, Matilde can build a beautiful and functional planter for their garden.

Step-by-Step Guide

To build a wooden planter in the shape of a right triangle, follow these steps:

  1. Determine the length of the existing bench, which will be one of the sides of the planter.
  2. Use the Pythagorean theorem to find the length of the other two sides.
  3. Cut the wood to the required length using a saw or a miter saw.
  4. Assemble the planter by attaching the sides together using screws or nails.
  5. Add a bottom to the planter using a piece of wood or a plastic sheet.
  6. Add a top to the planter using a piece of wood or a plastic sheet.
  7. Add any additional features, such as a trellis or a watering system.

Tips and Variations

  • Use a variety of woods to create a unique and visually appealing planter.
  • Add a trellis or a arbor to create a beautiful and functional planter.
  • Use a plastic or metal planter box to create a durable and low-maintenance planter.
  • Add a self-watering system to create a planter that is easy to maintain.

Conclusion

Q: What is the Pythagorean theorem, and how is it used in building a wooden planter?

A: The Pythagorean theorem is a mathematical concept that describes the relationship between the lengths of the sides of a right-angled triangle. It states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In building a wooden planter, the Pythagorean theorem is used to find the length of the other two sides, given the length of one side and the hypotenuse.

Q: How do I determine the length of the hypotenuse in a right triangle?

A: To determine the length of the hypotenuse, you can use the Pythagorean theorem. If you know the lengths of the other two sides, you can plug these values into the equation a^2 + b^2 = c^2, where a and b are the lengths of the other two sides, and c is the length of the hypotenuse.

Q: What is the difference between a right triangle and an oblique triangle?

A: A right triangle is a triangle with one right angle (90 degrees), while an oblique triangle is a triangle with no right angles. In building a wooden planter, a right triangle is typically used, as it allows for a more straightforward calculation of the lengths of the sides.

Q: Can I use a calculator to find the length of the hypotenuse?

A: Yes, you can use a calculator to find the length of the hypotenuse. Simply plug in the values of the other two sides into the Pythagorean theorem equation, and the calculator will give you the length of the hypotenuse.

Q: What are some common mistakes to avoid when building a wooden planter?

A: Some common mistakes to avoid when building a wooden planter include:

  • Using the wrong type of wood for the project
  • Not measuring the sides of the planter correctly
  • Not using the correct type of screws or nails for the project
  • Not assembling the planter correctly

Q: Can I use a pre-made planter box instead of building one from scratch?

A: Yes, you can use a pre-made planter box instead of building one from scratch. Pre-made planter boxes are available at most hardware stores and can be a convenient option for those who do not have the time or skills to build a planter from scratch.

Q: How do I maintain a wooden planter?

A: To maintain a wooden planter, you should:

  • Regularly clean the planter to prevent dirt and debris from building up
  • Apply a waterproof sealant to the planter to prevent water damage
  • Check the planter regularly for signs of wear and tear
  • Replace any damaged or worn-out parts of the planter

Q: Can I use a wooden planter in a high-traffic area?

A: Yes, you can use a wooden planter in a high-traffic area, but you should take extra precautions to ensure that the planter is durable and can withstand the wear and tear. You may want to consider using a planter made from a durable type of wood, such as cedar or redwood.

Q: How do I choose the right type of wood for my planter?

A: To choose the right type of wood for your planter, you should consider the following factors:

  • Durability: Choose a type of wood that is durable and can withstand the elements.
  • Aesthetics: Choose a type of wood that is visually appealing and fits with the style of your garden.
  • Budget: Choose a type of wood that fits within your budget.
  • Maintenance: Choose a type of wood that is easy to maintain and requires minimal upkeep.
