if the perimeter of a rectangular swimming pool is 76m, means 2%28L%2BW%29=76m
if the length L is 6m more than its widthW, then we have
L=W%2B6m...substitute in 2%28L%2BW%29=76m
2%28W%2B6m%2BW%29=76m ...sole for W
%28W%2B6m%2BW%29=76m%2F2
2W%2B6m+=38m
2W+=38m-6m
2W+=32m
W+=32m%2F2
highlight%28W+=16m%29
now find L
L=16m%2B6m
highlight%28L=22m%29
so, the dimensions of the swimming pool are:
highlight%28L=22m%29 and highlight%28W+=16m%29

the perimeter of a rectangular swimming pool is 76 meters. the length is 6 meters more than its width. find the dimensions of the swimming pool.
W=width; L=length=W+6m ; P=perimeter=2(L+W)=76 m
P=2(L+W)
76 m=2(L+W) Divide each side by 2.
38 m=L+W Substitute for L.
38 m=W+6m+W Subtract 6m from each side.
32 m=2W Divide each side by 2.
16 m=W ANSWER 1: The width is 16 meters.
L=W+6 m=16 m+6 m=22 m ANSWER 2: Length is 22 meters.
CHECK:
P=2(L+W)
76 m=2(22 m + 16 m)
76 m=2(38 m)
76 m=76 m
