The length Lof a soccer field is 40 yards more than its width W.
L=W%2B40yd..........1
Perimeter P is 380yd.

P=2%28L%2BW%29........2...substitute L and P
380yd=2%28W%2B40yd%2BW%29...solve for W
380yd%2F2=W%2B40yd%2BW
190yd=2W%2B40yd
190yd-40yd=2W
150yd=2W
150yd%2F2=W
highlight%2875yd=W%29.......now find the length
L=W%2B40yd..........1
L=75yd%2B40yd
highlight%28L=115yd%29
finally: the area A will be
A=L%2AW
A=115yd%2A75yd
A=8625yd%5E2
