Question

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

Answer 1

Answer:

Given - perimeter = 154

Length = 2m

TO find - Length and breadth of swimming pool

FOrmula using = 2(l+b)

Solution -Let the breadth be x

Length = 2+2x

we know that perimeter of a rectangle = 2(l+b)

= 2(l+b ) = 154

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

= 2+3x= 77

= 3x =75

= x = 25

$required \: breadth = 2 + 2 \times 25 = 52$

Length =25

Breadth = 52

Hope it is helpful for you

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
