Question

perimeter of a rectangular swimming pool is 154 its length is 2 metre more than twice its breadth what are the length and breadth??​

Answer 1

Answer:

52 m and 25 m

Step-by-step explanation:

let the length and breadth of the rectangular swimming pool be x m and y m respectively

as per the question

=> x = 2y + 2

=> x - 2y = 2. eq(1)

perimeter = 154

=> 2x + 2y = 154

=> x + y = 77. eq(2)

solving eq 1 and 2 we get

x+ y = 77

x - 2y = 2

--------------

3y = 75

y = 25

from eq 1 we get

x -2(25) = 2

x = 2 + 50

x = 52 m

Answer 2

Answer:

$\huge \bf \blue{Question}$

The perimeter of a rectangle swimming pool is 154 m.Its lengths is 2 m more than twice of its breadth.What are the length and the breadth of the pool?

$\huge \bf \blue{Answer}$

Let breadth=x metre

Hence,breadth=(2x+2)metre

Perimeter of rectangle pool=154

2(l+b)=154

2(2x+2+x)=154

3x+2=154/2=77

3x+2=77

3x=77-2

3x=75

x=75/3

x=25 metre

Breadth=>x=25 metre

Length=>

2x+2

2(25)+2

50+2

52 metre

Hence the answers are 25 metre and 52 metre.
