A trapezoid is 10 feet tall and has an area of 80 square feet. One base of the trapezoid is 2 feet shorter than the other base. What is length of the two bases of the trapezoid?

Answer 1

Area = h/2 ( base1 + base2)

80 = 10/2 ( x + x-2)

80 = 5(2x-2)

80 = 10x - 10

90 = 10x

x=9

The bases are 9 and 7
