Question

The perimeter of a rectangular swimming pool is 154m. Its length 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 the Rectangle = 2(l + b)

$2 \times (l \times b) = > 154$

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

$2 \times ( 2 + 3x) = > 154</p><p>$

$</p><p>2 + 3x = > 77</p><p>$

$3x = 75$

$x = > 25m$

$required \: breadth = > 25m$

$Length = 2 + 2 \times 25 = > 52m$

$Hope\:it\:Helps$

Answer 2

perimeter of rectangular pool=2(a+b)
let breadth,b be=x
and length,a be =(2x+2)m
therefore,
perimeter=2(x+2x+2)=154m
3x+2=154/2
x=75/3=25m
breadth=25m
length=52m
