Question

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

Answer 1

Step-by-step explanation:

lets us consider that breath of the pool is=x

and length is y.

y+2 (given)

formula for perimeter:

2×length +breath=perimeter

2×y+x=154

4y+x=154

x=154÷4

x=38.5

therefore breath=38.5

length=y+2=38.5+2=40.5

Answer 2

Question :–

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

Given :–

1. Perimeter of a rectangular swimming pool = 154m.
2. Its length is 2m more than twice its breadth.

To Find :–

1. The length of the pool.
2. The Breadth of the pool.

Solution :–

Let the breadth = x

And the length = 2x + 2

Perimeter of rectangle = $2(l+b)$

$2(l+b) = 154$

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

$2(3x + 2) = 154$

$3x + 2 = \sf \dfrac{\cancel{154}}{\cancel2}$

$3x + 2 = 77$

$3x = 77 - 2$

$3x = 75$

$x = \sf \dfrac{75}{3}$

$x = 25$

Hence,

The breadth of the pool :-

x = 25m.

And the length of the pool

= 2x + 2

= 2 × 25 + 2

= 50 + 2

= 52m.

Answers :–

1. Breadth of the pool = 25m.
2. Length of the pool = 52m.
