Question

The perimeter of a rectangular swimming pool is 154m. it's length is 2mbmore than twice it's breadth. what are the length and breadth of the pool​

Answer 1

Given,

Perimeter of a Rectangular swimming pool = 154m

length is 2m more than the breadth.

let the breadth of Rectangular swimming pool be x

length be 2x + 2

According to the problem,

2(2x + x + 2 ) = 154

2(2x + x + 2) = 154

6x + 4 = 154

6x = 154 - 4

6x = 150

x = 150/6

x = 25

Breadth = x = 25

length = 2x + 2 = 2(25) + 2 = 52

Therefore, the length and breadth are 25 and 52.

Answer 2

Answer

Let [x] be the breadth

$length \: = 2 + 2x$

Perimeter of a rectangle

2(Length + Breath)

$2( + b) = 154$

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

$2(2 + 3x) = 154$

$2 + 3x = 77$

$3x = 75$

$x = 25meter$

$length = 25meter$

$breath = 52metre$

Hence, answer proved
