Problema Solution

The Width of a rectangle is 3 meters more than it's length. The perimeter is 26 meters, find the length.

Answer provided by our tutors

let


l = the length of the rectangle

w = the width of the rectangle


the width of a rectangle is 3 meters more than it's length


w = 3 + l


the perimeter is 26 meters:


2(l + w) = 26 divide both sides by 2


l + w = 13


by solving the system of equations:


w = 3 + l

l + w = 13


we find


w = 8 m


l = 5 m
