Answer:
24 ft
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{h}{2}[/tex](a + b)
where h is the height and a, b the parallel bases
let a = 12 and find b, that is
[tex]\frac{8}{2}[/tex](12 + b) = 144
4(12 + b) = 144 ( divide both sides by 4 )
12 + b =36 ( subtract 12 from both sides )
b = 24
The length of the other base is 24 ft
