Question

perimeter of rectengular swmming pool is 154m.its length is 2m more than twice its dreath.what are the length and breath of the pool?

Answer 1

←→←→←→←→★←→←→←→←→

Perimeter =154

2(l+b)=154

l+b=77

now,

let the breadth be x then length is 2x+2
then,

l+b=77

2x+x+2=77

3x=77-2

3x=75

x=25

hence length and breadth are:

x=25

&

(2x+2)=52

Answer 2

let breadth be x

then length = 2x+2

Now A/Q

perimeter=2( l+b )

154=2( 2x+2+x )

154/2=2x+2+x

77=3x+2

77-2=3x

x=75/3

x=25

So,length=25×2+2=52cm ans.

and breadth=25cm. ans.
