You can put this solution on YOUR website!
Assign variables:
L = length
w = width

Translate description into symbols:
2L%2B2w=124, and L=w%2B8


Your mistake was trying to divide the perimeter equation by FOUR. Instead, look carefully at it; and divide both members by TWO.
-----You should obtain L%2Bw=62.
