The length of a rectangular swimming pool is exactly three times as long as its width. If the pool has a perimeter of 400m find the width of the pool.

50m

Step-by-step explanation:

let the width be x

length=3x

3x+3x+x+x=400

8x=400

x=400÷8

x=50

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
