Question 337583: The perimeter of a rectangular swimming pool is 210 meters. The length of the pool is double the width. Find the length and width of the pool.
P=210, P=2L+2W L=2W
210 = 2(2W)+2W
210 = 4W+2W
210 = 6W
210/6 = W
W=35 METERS
L = 2W)=2(35) = 70 METERS

let width =x
length =2x
perimeter =210m
perimeter =2(l+w)
2(l+w) =210m
2(2x+x)=210
2(3x) =210
6x=210
x=210/6
x=35
ie,
width = 35m
length =2*35 =70m

The perimeter of a rectangular swimming pool is 210 meters. The length of the pool is double the width. Find the length and width of the pool.
P=210, P=2L+2W L=2W
210 = 2(2W)+2W
210 = 4W+2W
210 = 6W
210/6 = W
W=35 METERS
L = 2W)=2(35) = 70 METERS
