Need . answer question in picture.

A = 1/2(b X h)
20.025 = 1/2(8.9 X u)
20.025*2/1= 1/2 * 2/1(8.9 x u)
40.05 =8.9u
40.05/8.9 = 8.9u/8.9
u = 4.50

Check
A = 1/2(b X h)
A = 1/2(8.9 X 4.5)
A = 1/2(40.05)
A = 20.025 in²

Ithink the answer is b i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you
