You can put this solution on YOUR website!
You are given 2 equations with 2 unkowns. That means you can solve it! The two equations are:
Eqn #1: L=4W
Eqn #2: 2L%2B2W=150
substitute the expression for l into Eqn. #2:
2%284W%29%2B2W=150
10W=150
highlight%28W=15%29
Now, you can plug in the value of W into Eqn #1 and solve for L. I will leave that part up to you.
Good Luck,
