Answer:
B. 93.75 ft
Explanation:
The area of a trapezoid is found by the equation Area=1/2(base 1 + base 2)*height
Known:
Base 1 = 12.5 ft
Base 2 = .5*Base 1 = .5*12.5 = 6.25 ft
Height = 10 ft
We can plug these numbers into the formula
Area=1/2(12.5+6.25)*10
Solving the equation, we get Area = 93.75 ft
