Question 307169
what is the perimeter of a rectangle that has an area of 12,150 square feet? the ratio of length to width is 3:2.

Let the two sides of the rectangle be 3x and 2x respectively. Then we have:

3x*2x = 12150
6x^2 = 12150
x^2 = 2025
x = 45

The two sides then are 2*45 = 90 and 3*45 = 135
