Area of Trapezoid = h(b1+b2/2)
b1 and b2 are the lengths of each base and h is the height.

Area = 16(20+24/2)=352 Square Feet

352/20=17.6 Cans of paint.

Hope this helps and is correct, I haven't done this kind of math in a while.

Answer:

18

Explanation:

Since you can see the area you can divide that by 20 and you will get 17.6 but since decimals don't work in this type of question round it to 18 and that is the final answer!
