Hello!
To find the area of a trapezoid you use the equation
[tex] A = \frac{a + b}{2} h [/tex]
A is area
a and b are the base length
h is height
Put in the values you know
[tex]A = \frac{20 + 25}{2} * 15[/tex]
Add
[tex]A = \frac{45}{2} * 15[/tex]
Divide
[tex]A = 22.5 * 15[/tex]
Multiply
A = 337.5
The answer is B) 337.5 ft squared
Hope this helps!
