Question

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

Answer 1

Let the breadth be 'x'

Length = 2 + 2x

Now 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 = 25 m

Required breadth = 25 m
Length = 2 + 2 x 25 = 52 m

Hope This Helps You!

Answer 2

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


I hope this will help u :)
