Question

The perimeter of a rectangular swimming pool is 154m. Its length is 2m more than twice its breadth.

What are the length and the breadth of the pool?

​

Answer 1

Answer:

Step-by-step explanation:

P=154m

L=l

B=2l

Acc to que

Per of a rec =2(l+b)

154m=2(l+2l)

154/2=3l

77=3l

77/3=l

22.3m=l

So

Bredth=2×22.3

=44.6m

Hope it helps u

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
