Question

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

Answer 1

Given : perimeter of rectangular swimming pool = 154 cm

length is 2m more than twice it's breadth

To find : length and breadth

Solution : let breadth be × m

➡length = 2 × 2 m

perimeter = 2( l+b )

154 = 2 [ ( 2x + 2 ) + x ]

154 = 2 [ 2x + 2+ x]

154 = 2 [ 3x + 2 ]

154/2 = 3x + 2

77-2 = 3x

➡x = 25

Answer :

Length = 2x + 2 = 52m

breadth = 25m
