Tracy needs to find the length of the equipment storage room where she works. The room is one meter longer than it is wide. Its perimeter is 14 meters.
-------------------
How would she know the perimeter if she doesn't know the length?
Ignoring that,
P = 2W + 2L = 14
W + L = 7
L = W + 1
Sub for L in the 1st eqn
W + L = 7
W + (W+1) = 7
2W + 1 = 7
2W = 6
W = 3
-------
L = 4
