Perimeter=2(L+W)=360 meters; L=3W+3
Substituting for L, solve for W:
2((3W+3)+W)=360 m
2(3W+3+W)=360 m
2(4W+3)=360 m
8W+6=360 m
8W=354 m
W=354%2F8=44.25 m ANSWER 1 Width
L=3W+3=3(44.25 m)+3=135.75 m ANSWER 2 Length
CHECK:
Perimeter=2(L+W)=360 m
Perimeter=2(135.75 m + 44.25 m)=360 m
Perimeter=2(180 m)=360 m
Perimeter=360 m = 360 m
