The perimeter of a rectangular 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?

Let the breadth be x m. The length will be (2x + 2) m. 

Perimeter of swimming pool = 2(l + b) = 154 m

2(2x + 2 + x) = 154

2(3x + 2) = 154

Dividing both sides by 2, we obtain

293X + 2/2 = 154/2

3x + 2 = 77

On transposing 2 to R.H.S, we obtain

3x = 77 − 2

3x = 75

On dividing both sides by 3, we obtain

x = 25

2x +2 = 2 x 25+2 = 52

Hence, the breadth and length of the pool are 25 m and 52 m respectively.

let length be 2x+2
breath will be x
According to questions
Peremeter=154m
2(2x+2+x)=154m
2(3x+2)=154m
6x+4=154m
6x=150m
x=25m
breath=25m
length=52m.
