Answer:
252 [tex]cm^{2}[/tex]
Step-by-step explanation:
To find the area of a trapezoid, you must add both the bases up then divide by two. After that you must multiply that by the height.
[tex]\frac{a+b}{2} h[/tex] here is the formula where a and b are the bases.
[tex]\frac{20+16}{2} * 7[/tex]
Simplify.
[tex]\frac{36}{2} * 7\\\\18*7\\= 126[/tex]
That is the area of one trapezoid and since there are two of the same trapezoids, you must multiply by two.
[tex]126 * 2 = 252[/tex]
Therefore your answer is 252 cm^2.
