Question

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

Answer 1

Answer:

For the rectangular swimming pool,

P=154m

l= 2+2b

b=?

P=2 (l+b)

154/2=2+2b+b

77-2=3b

75=3b

b=25cm

l=2+2b

= 2+2×25

2+50

l=52 cm.

The length and breadth is 52 and 25 cm respectively.

Answer 2

Given :

• Perimeter = 154m

____________________________

To Find :

• Length and the breadth

____________________________

Solution :

Let x be the measure of the breadth

According to the question :

→ Length = 2x + 2

2(length + breadth) = Perimeter of the rectangle

⇒ 2 {(2x+2) + x} = 154m

⇒ 2(2x + 2 + x) = 154m

⇒ 2(3x + 2) = 154m

⇒ 6x + 4 = 154m

⇒ 6x = 154m - 4

⇒ x = 150/6

⇒ x = 25m

Finding out length and breadth :

→ L = 2x+2 = 52

→ B = x → 25

∴ Length of rectangle is 52 m and breadth is 25 m
