Question

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

Answer 1

GIVEN :

The perimeter of a rectangular pool = 154m²

Length is 2m more than twice the breadth

Let the breadth of rectangular pool be x

Length of the pool be 2x + 2

We know that,

Perimeter of Rectangle = 2 [ Length + Breadth ]

According to the problem,

2 [ ( 2x + 2 ) + x ] = 154

3x + 2 = 154/2

3x + 2 = 77

3x = 77 - 2

3x = 75

x = 75/3

x = 25

Breadth of rectangular pool = 25m

Length of the pool = 2x + 2 = 50 + 2 = 52m

Therefore, 52m and 25m are the length and breadth of rectangular pool respectively.

Answer 2

Answer:

Step-by-step explanation:

Let breadth be x

Perimeter=154m

Length= 2+2x

Breadth=x

Thus,

Perimeter of rectangle= 2(l+b)

154 =2(2+2x+x)

154 =2(2+3x)

154/2 = 2+3x

77= 2+3x

77-2=3x

75=3x

75/3=x

25=x

Length=2+2x=2+2xx=52

Breadth=25

Thankyou!
