What is the area of the rectangle above in terms of $x$ and $y?$ But this area is 420 square centimeters so this gives you an equation in $x$ and $y.$ Since the figures are made from the same wire their perimeters are the same. This gives you a second equation in $x$ and $y.$ Solve the pair of equations for $x$ and $y.$ Penny
