Question

the perimeter of a rectangular swimming pool is 154m. It's length is 2m more than twice it's breadth. what are the length and breadth of the pool​

Answer 1

Step-by-step explanation:

Let the breadth be = x

Length = 2 + 2x

perimeter of a rectangle = 2(l + b)

2 (l + b) = 154

2 ( 2 + 2x + x) = 154

2 ( 2 + 3x) = 154

2 + 3x = 77

3x = 75

x= 75 ÷ 3

x = 25 m

Required breadth = 25 m

hence, Length = 2 + 2 x 25 = 52 m

hope this helps :)
