Problema Solution
Suppose that the length of a certain rectangle is 4 meters less than four times its width. The perimeter of the rectangle is 52 meters. Find the length and width of the rectangle.
Answer provided by our tutors
let width = x , length = 4x-4
perimeter = 52
2(4x+x-4) = 52
5x-4 = 26
5x = 30
x = 6
width = 6 m ,length = 4*6-4 = 20m
