Answer:
The answer is 12 cm
Step-by-step explanation:
Let b = base of parallelogram; then, (b − 4) = height of the parallelogram
A = bh
96 = b(b − 4)
96 = b2 − 4b
0 = b2 − 4b − 96
0 = (b − 12)(b + 8)
b −12 = 0
b = 12
b + 8 = 0
b = − 8
Since length is always positive, the length of the base is 12 cm.
