Question

The formula for the atrapezoid is Ah bi b2). Express bi in number of feet inarea of terms the of a trapezoid is 60 square feet, its height is 6 ft, and one base is 12 Find other base.

Answer 1

Area = 1/2h(b1 + b2)

60 = 1/2(6)(b1 +12)
60 = 3(b1 +12)
60 = 3b1 + 36
24 = 3b1
24/3 = b1

b1 = 8

The other base is 8 feet
