Question

The perimetre of a rectangular swimming pool is 154m its lenght is 2m more than twice its breath what are the lenght and the breath of the pool?

Answer 1

heu dude

perimeter=154cm

let breadth be x cm

then lenght =2x+2


according to question

2(2x+2+x)=154
2(3x+2)=154
3x+2=77
3x=75
x=25


so breadth =25cm
and lenght =52cm

hope it helps u

Answer 2

Hiii!!!

Here's Ur answer...

ATQ, length of the rectangular swimming pool is 2m more than twice of its breadth.

Let breadth be x.

Therefore length is 2x + 2

Perimeter of the swimmers pool = 154m

==> 2 ( l + b ) = 154m

==> 2 ( 2x + 2 + x ) = 154m

==> 3x + 2 = 154/2

==> 3x + 2 = 77m

==> 3x = 77 - 2

==> 3x = 75

==> x = 75/3

==> x = 25m

Hence, breadth of the swimming pool = x = 25m

Length of the swimming pool = 2x + 2 = ( 2 × 25 ) + 2 = 50 + 2 = 52m

Hope this helps..!!
