Question

the length of a rectangular pool is three times its width. The perimeter of the rectangular pool is 168 feet. find the length and width of the pool.

Answer 1

Step-by-step explanation:

breadth = 21 m

length = 63 m

Answer 2

• Answer:

w = 21 feet

l = 63 feet

• Step-by-step explanation:

l = 3w

P = 2(l + w)

168 = 2(l + w) : 2

84 = l  + w

replace l

84 = 3w + w

4w = 84

w = 84 : 4

w = 21 feet

l = 3w

l = 3×21 feet

l = 63 feet
