Problema Solution

the permeter of a rectangle is 60 inches. the lenght is 8 inches greater than the width. find the width and the lenght

Answer provided by our tutors

let


l = length of the rectangle

w = width of the rectangle

P = 60 in the perimeter of the rectangle


the length of a rectangle is 8 inches greater than the width


l = 8 + w


the formula for the perimeter is P = 2*(w + l) so


2*(w + l) = 60


by solving the system of equations


l = 8 + w

2*(w + l) = 60


we find


l = 19 in

w = 11 in


the width is 11 in and the length is 19 in.
