The area of a trapezoid is:
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 = (10/2)(2.5)
A = (5)(2.5)
A = 12.5

Step-by-step explanation:
The formula for simple interest is I = PRT where I is the interest paid/earned, P is the principal amount deposited/invested, R is the rate as a decimal, and T = time in years.
