Problema Solution

The perimeter of a rectangle is 40 ft, the length is 8ft longer than the width. Find the dimensions.

Answer provided by our tutors

let


l = the length of the rectangle

w = the width of the rectangle


the perimeter of a rectangle is 40 ft


2(l + w) = 40


the length is 8ft longer than the width


l = 8 + w


by solving the system of equations


2(l + w) = 40

l = 8 + w


we find the dimensions


l = 14 ft


w = 6 ft
