You can put this solution on YOUR website!
The width ( W SAY) of a retangle is 15 feet less than its length( L SAY), and
W =L-15

the perimeter( P SAY) is 210 feet.
P= 2L + 2W
210 = 2L +2(L-15)=2L+2L-30=4L-30
4L-30=210
4L=210+30=240
L=240/4 = 60
W = 60-15 =45


Can you show me how to find the width and the length.
