What is a Trapezoid?

A trapezoid is a quadrilateral with at least one pair of parallel sides. It has four sides, and the parallel sides are called the bases. The area of a trapezoid can be calculated using a simple formula, which we will explore in this article.

The Formula for the Area of a Trapezoid

The formula for the area of a trapezoid is:

A=12(b1+b2)h{ A = \frac{1}{2} (b_1 + b_2) h }

Where:

  • A{ A } is the area of the trapezoid
  • b1{ b_1 } and b2{ b_2 } are the lengths of the two bases
  • h{ h } is the height of the trapezoid

Julio's Work

Let's say Julio wants to find the area of a trapezoid with bases of 11 inches and 6 inches, and a height of 6 inches. He can use the formula above to calculate the area.

{ 11 \times 6 = 6 \, \text{in} \}

However, this expression is incomplete and does not follow the formula for the area of a trapezoid. To find the area, Julio should use the formula:

A=12(b1+b2)h{ A = \frac{1}{2} (b_1 + b_2) h }

Substituting the values, we get:

A=12(11+6)6{ A = \frac{1}{2} (11 + 6) 6 }

A=12(17)6{ A = \frac{1}{2} (17) 6 }

A=12×102{ A = \frac{1}{2} \times 102 }

A=51 in2{ A = 51 \, \text{in}^2 }

Explanation

In the above example, Julio incorrectly used the expression 11×6=6 in{ 11 \times 6 = 6 \, \text{in} } to find the area of the trapezoid. This expression is actually the result of multiplying 11 and 6, which equals 66. However, this is not the correct way to find the area of a trapezoid.

To find the area of a trapezoid, we need to use the formula A=12(b1+b2)h{ A = \frac{1}{2} (b_1 + b_2) h }, where b1{ b_1 } and b2{ b_2 } are the lengths of the two bases, and h{ h } is the height of the trapezoid.

Conclusion

In conclusion, Julio's work using the expression 11×6=6 in{ 11 \times 6 = 6 \, \text{in} } to find the area of a trapezoid is incorrect. The correct way to find the area of a trapezoid is to use the formula A=12(b1+b2)h{ A = \frac{1}{2} (b_1 + b_2) h }, where b1{ b_1 } and b2{ b_2 } are the lengths of the two bases, and h{ h } is the height of the trapezoid.
