The area of a trapezoid whose bases have lengths b1 and b2 and altitude has length of h is given by A = $\frac{1}{2}$*h(b1+b2) Given Area A= 96 $cm^{2}$ h = 8 cm b1 = 9cm Therefore 96 = $\frac{1}{2}$*8* (9 + b2) 96 = 36 + 4 b2 4b2 = 96 - 36 4b2 = 60 b2 = $\frac{60}{4}$ = 15 cm Length of the other base side = 15 cm
