1 Answer
Trapezoid has bases
Its area is
Parallelogram:
Triangle:
Explanation:
Consider a trapezoid with bases
If
So, the area of parallelogram can be obtained using a formula for an area of parallelogram, taking into consideration
If
So, the area of triangle can be obtained using a formula for an area of parallelogram, taking into consideration
