The perimeter of a rectangle is 24 ft the length is 4 ft longer than the width. Find the dimensions. Write a system of linear equations and solve the resulting system. Let x be the length and w be the width.

Write the first equation

2x+2y=24

The second equation is x-y =4

We solve it

x = 8

y = 4

So the length is 8 ft and width 4 ft
