Answer:

14,800in^2

Explanation:

ok so to find the area of a trapezoid, we use the equation A=((a+b)/2)h. So Area is equal to base a (the one on the top) plus base b (the one on the bottom) divided by two (so a+b/2) and then multiply that number by h (the height. So we do it like this

(145+225)/2 x 80

But remember, we follow PEMDAS, so we multiply first

(a+b)80

370(80)= 29600

now we can divide

29600/2= 14,800sq in (or in^2)
