The area of a trapezoid is:
![A = \frac{a + b}{2} h](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7Ba%20%2B%20b%7D%7B2%7D%20h)
A = area
a = base 1
b = base 2
h = height
Area = unknown
base 1 = 2.5
base 2 = 7.5
height = 2.5
^^^Plug these numbers into the formula!
![A = (\frac{2.5 + 7.5}{2} )(2.5)](https://tex.z-dn.net/?f=A%20%3D%20%28%5Cfrac%7B2.5%20%2B%207.5%7D%7B2%7D%20%29%282.5%29)
A = (10/2)(2.5)
A = (5)(2.5)
A = 12.5
Hope this helped!

The answer to your question is D
3.5 gallons
1 gallon = 4 quarts
