Question

the perimeter of a rectangular swimming pool is 154m it's length is 2 more than its breadth are the length and breadth of the pool and find the area of the pool
​

Answer 1

Answer:

The perimeter of rectangular swimming pool is 154m

length is 2more than its breath

Step-by-step explanation:

let the breath of swimming pool is = x

length = 2x

perimeter of swimming pool is 2×(l+b) = 154 m

2×( 2x+x) = 154

4x +2x = 154

6x = 154

x = 154/6

25.66

length = 2×25.66 = 51.32

breath is = 25.66

area of swimming pool is = l×b

51.32× 25.66

1316.87 m^2

Answer 2

Given :

The Perimeter of a rectangular swimming pool is 154 m.

Length is 2 m more than twice its breadth.

To Find :

Length and Breadth of the pool .

Solution :

$\longmapsto\tt{Let\:breadth\:be=x}$

As Given that length is 2 m more than twice its breadth. So ,

$\longmapsto\tt{Length=2x+2}$

Using Formula :

$\longmapsto\tt\boxed{Perimeter\:of\:Rectangle=2(l+b)}$

Putting Values :

$\longmapsto\tt{154=2(2x+2+x)}$

$\longmapsto\tt{\cancel\dfrac{154}{2}=3x+2}$

$\longmapsto\tt{77-2=3x}$

$\longmapsto\tt{75=3x}$

$\longmapsto\tt{x=\cancel\dfrac{75}{3}}$

$\purple\longmapsto\:\large\underline{\boxed{\bf\blue{x}\pink{=}\red{25}}}$

Therefore :

$\longmapsto\tt{Length\:of\:pool=2(25)+2}$

$\longmapsto\tt\bf{52\:m}$

$\longmapsto\tt{Breadth\:of\:pool=x}$

$\longmapsto\tt\bf{25\:m}$
