Question

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

Answer 1

let the breadth be x
and length is 2+2x
perimeter =2(x+2+2x)
154/2=2+3x
77-2=3x
75/3=x
25=x
breadth=25m
length =2+50=52m

Answer 2

Let the breadth is x and then length will be 2x+2

Then

Perimeter of rectangle =2(x+2x+2)

Perimeter of rectangle =2(3x+2)

154=2(3x+2)

154/2=3x+2

77=3x+2

77-2=3x

75/3=x

25=x

Then

Breadth =25m

And length =2(25)+2

Length =52+2

Length =52
