If the area of the figure is 128 inches squared. What is the perimeter? The measurements are 4 and 5x+7

Answer 1

Assuming the figure is a rectangle (which is not stated in the question),

LW = A

4(5x + 7) = 128

x = [(128 / 4) - 7] / 5 = 5

P = 2(L + W) = 2[4 + (5x + 7)] = ?

Pug in x=5 and finish from here.
