Question

What is the area of the trapezoid with height 13 units?

Answer 1

The area would be 286cm^2.
The formula for finding the area of a trapezoid is $\frac{a+b}{2} h$

plug in the numbers in the formula:
15+29/2 * 13 = 286 

I hope this helps! :)

Answer 2

A = 1/2(15+7+15+7)(13)
A= 1/2(44)(13)
A = 286
