A rectangular room is 4 meters longer than it is wide, and its perimeter is 28 meters. Find the dimension of the room.

Well you would start by drawing a rectangle. Label one side W and One side (W+4) then you would set up this equation

2 (W+4) + 2W=28

2W+8+2W=28

4W+8=28

4W=20

W=5

So that's the width then you will plug it into (W+4)

(5+4) = 9

So you have a room that has a length of 9 and a width of 4
