x -----> the length of rectangle
y ----> the height of rectangle
h ----> height of trapezoid
Applying the Trapezoid Mid-segment Theorem we have that
----> equation A
---->
----> equation B
Remember that
The area of rectangle is equal to
The area of trapezoid is equal to
-----> equation C
substitute equation A and equation B in equation C
The area of trapezoid is two times the area of rectangle
therefore
The area of trapezoid is 20 square centimeters
