Question

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

​

Answer 1

Answer:

Step-by-step explanation:

given,perimeter of a rectangular swimming pool is 154m

let 'l' be the length of the swimming pool

and 'b' be the breadth of the swimming pool...

now, perimeter is 2(l+b)=154

(l+b)=77------(1)

given,length is 2 m more than twice it's breadth

l=2b+2 -----(2)

by substituting (2) in (1)

2b+2+b=77

3b=75

b=25 by substituting this value in (1)

l+25=77

l=52

therefore 52m and 25m are the length and breadth of the rectangular swimming pool respectively
