The area of a rectangle is 92 square units. If the length is 5 times the width, then find the dimensions of the rectangle.

Question

The area of a rectangle is  square units. If the length is  times the width, then find the dimensions of the rectangle.

Answer 1

A=LW = 92

L=5W

92 = 5W(W) = 5W^2

W^2 = 92/5

W = sqr(92/5) = sqr18.4 = about 4.29 wide

L= 5(4.29) = 21.45 long

21.45 x 4.29 = 92.02, off by .02 due to rounding approximations
