Question

The perimeter of a rectangular swimming pool is 154 metre to metre more than twice its breadth what are the length and the breadth of the pool

Answer 1

Answer:

as per given

l = 25

b = 52

Explanation:

let l be x

b = 2l + 2

b = 2l + 2

2( 2x + 2 + x ) = 154

2( 3x + 2 ) = 154

6x + 4 = 154

6x = 154 - 4

6x = 150

x = 25

l = 25

b = 2l + 2

b = 2( 25 ) + 2

b = 52

Answer 2

Answer:

Breadth = 25 m

Length = 52 m

Step-By-Step Explanation:

Given that,

Perimeter of rectangular swimming pool = 154 m

Let the breadth of rectangle be = x

According to the question,

Length of the rectangle = 2x + 2

We know that,

Perimeter = 2(length + breadth)

⇒ 2(2x + 2 + x) = 154 m

⇒ 2(3x + 2) = 154

⇒ 3x +2 = 154/2

⇒ 3x = 77 – 2

⇒ 3x = 75

⇒ x = 75/3

⇒ x = 25 m

Therefore, Breadth = x = 25 cm

Length = 2x + 2

= (2 × 25) + 2

= 50 + 2

= 52 m
