Question

A trapezoid has an area of 22 square inches. The longer base measures 6 inches and the height is 4 inches. use the formula
`A= (1)/(2)h( b_(1)+ b_(2) )` to find the length of the shorter base.

a. b = 10
b. b = 5
c. b = 7.5
d. b = 12.5

Answer 1

22=1/2*4(6+b)
22=2(6+b)
22=12+2b
10=2b
Divide both sides by 2:
b=5
The answer is b.

Hope this helps :)
