Answer:
108 Ft^2
Explanation:
So the formula for finding the area of a trapezoid is Area= 1/2(a+b)*h
So in this equation, your a=6ft and your b=18ft and your h=9ft
Add the two parallel lines (a and b) and then divide that product by 2. Then multiply that product by 9.
This should give you a total of 108 ft^2 (squared)
Hope this helps!
