Question 33090
Start with the formula for the perimeter of a rectangle.
{{{P = 2(L+W)}}} But L = W+4 and P = 4254 feet, so:
{{{424 = 2(W+4+W)}}}
{{{424 = 2(4+2W)}}}
{{{424 = 8+4W}}} Subtract 8 from both sides of the equation.
{{{416 = 4W}}} Divide both sides by 4.
{{{104 = W}}}feet and 
{{{L = W+4}}} 
{{{L = 104 + 4}}}
{{{L = 108}}}feet
