Question 247553
The perimeter of a rectangle is the sum of all of its sides.
Since a rectangle has four sides, the standard equation is:
{{{P=2L+2W}}}


However, our problem tells us the length is 4 times the width, so let:
x = width
4x = lenght


Therefore, our equation becomes: {{{P=2(4x)+2(x)}}}


{{{200=8x+2x}}}
{{{200=10x}}}
{{{x=20}}}


Each width measures 20 feet, each lenght measures 20 feet x 4 = 80 feet.


Check: {{{20+20+80+80=200}}}
