Hello!
You can make two expressions based on what you know
2l + 2w = 52
w = l - 2
You can put w in the first equation
2l + 2(l - 2) = 52
Distribute the 2
2l + 2l - 4 = 52
Combine like terms
4l - 4 = 52
Add 4 to both sides
4l = 56
Divide both sides by 4
l = 14
We can put this into the second equation to get the width
w = 14 - 2
w = 12
The length is 14 and the width is 12
Hope this helps!
