You can put this solution on YOUR website!
From the given information, you may write an equation for the length in terms of the width as follows:
Equation #1:
You also know the perimeter, so you may write an equation for that in terms of l and w:
Equation #2:
Now you have 2 equations and two unknowns. That means you can solve for the two unknowns. First substitute your value of l in Equation #1 into Equation #2:

And solve for w:

cm
Now that you know the value of w, you can substitute that value back into Equation #1 and solve for l. I will leave that part of the problem up to you.
Good Luck,
