Question

 Tracy needs to find the length and width of the equipment storage room where she works. The room is 3 meters longer than it is wide. Its perimeter is 18 meters. What is the width of the storage room?

Answer 1

Hy devin ,

 

remember how the perimeter of a rectangle works

 

perimeter = 2L + 2W

 

the L is for length and the W for width

 

Now 

 

L = W + 3

 

 

since we are given that it's 3m longer than the width

 

Now substitute

 

2W + 6 + 2W = 18

 

4W = 12

 

The width of your room would be 3m.

 

good luck.
