Question

The area of a trapezoid is 60 square feet, its height is 6 ft, and one base is 12 ft. What is the number of feet in the other base?

Answer 1

8 ft

Explanation:

the calculate for area is
`S= (B+b)/2 xx h`
Hence you can have the sum of the bases
`(B+b) =( 2 S)/h = 2 xx (60 ft^2)/(6ft) = 20 ft`
Hence
`b= (B+b) -12 ft = 20 ft-12 ft= 8 ft`
