Me 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. find the width in meters

I realise this is quite late but in case you still wanted the answer, the width is 3m.

If the length is 3m longer than the width, you can write the width as x and the length as x + 3. The perimeter would be both lengths and both widths added together, so you would just write it as:
x + x + x + 3 + x + 3 = 18
4x + 6 = 18
- 6
4x = 12
÷ 4
x = 3

I hope this helps!

4, -4 is the other point it would pass through
