Question

the perimeter of a swimming pool is 154 m.Its length is 2 m more than twice its breadth .What are the length and the breadth of the pool?

Answer 1

Perimeter of swimming pool is 154

Length is 2 more than twice its breadth

Therefore

l = 2b + 2

Perimeter = 2 ( l + b )

154 = 2 ( 2b + 2 + b )

154 = 2 ( 3b + 2 )

6b + 4 = 154

6b = 154 - 4

6b = 150

b = 150 / 6

b = 25

l = 2b + 2

l = 2 × 25 + 2

l = 50 + 2

l = 52

So Length = 52m

Breadth = 25m

Hope it helps you.

Have a good day.
