Answer 1

if the area of a rectangle is132, height is 8,length is (3x-6) length equals?

Area is length times width, or in this case, length times height.

8 * (3x - 6) = 132

24x - 48 = 132

24x = 132 + 48 = 180

x = 180 / 24 = 7.5

length = (3x - 6) = (3 * 7.5) - 6 = 22.5 - 6 = 16.5

8 * 16.5 = 132    verified
