Problem Statement
A rice field is in the shape of a trapezoid, with parallel sides of length 50m and 80m. The distance between the parallel sides is 30m. What is the area of the rice field?
Given Facts
- The length of the shorter parallel side (base) is 50m.
- The length of the longer parallel side (base) is 80m.
- The distance between the parallel sides (height) is 30m.
Formula to Solve the Problem
The formula to find the area of a trapezoid is:
Area = (1/2) × (sum of parallel sides) × height
Solution
To find the area of the rice field, we need to plug in the given values into the formula.
First, we need to find the sum of the parallel sides:
sum of parallel sides = 50m + 80m = 130m
Now, we can plug in the values into the formula:
Area = (1/2) × 130m × 30m Area = (1/2) × 3900m² Area = 1950m²
Therefore, the area of the rice field is 1950 square meters.
Discussion
The problem requires us to find the area of a trapezoid, which is a type of quadrilateral with two parallel sides. The formula to find the area of a trapezoid is given by:
Area = (1/2) × (sum of parallel sides) × height
This formula can be derived by dividing the trapezoid into two triangles and a rectangle. The sum of the areas of these two triangles and the rectangle is equal to the area of the trapezoid.
The solution to the problem involves plugging in the given values into the formula and simplifying the expression. The final answer is the area of the rice field, which is 1950 square meters.
Real-World Applications
The problem of finding the area of a trapezoid has many real-world applications. For example, in architecture, the area of a trapezoid can be used to find the area of a roof or a wall. In engineering, the area of a trapezoid can be used to find the area of a beam or a column.
Conclusion
In conclusion, the problem of finding the area of a trapezoid is a simple yet important problem in mathematics. The formula to find the area of a trapezoid is given by:
Area = (1/2) × (sum of parallel sides) × height
This formula can be used to find the area of a trapezoid in many real-world applications. The solution to the problem involves plugging in the given values into the formula and simplifying the expression. The final answer is the area of the rice field, which is 1950 square meters.
