Question

perimeter of rectangular swimming pool is 154 metre its length is 12 metre more than twice its breadth find length and breadth of pool

Answer 1

Perimeter = 2 ( L + B )

Perimeter of rectangular field = 154 metre

2 ( 12m + B ) = 154 m

24 m + 2B = 154 m

2b = 154m - 24 m

2b = 130 m

B = 130 / 2 m

B = 65 m

My answer is correct

Answer 2

Answer:

Breadth = 21.16 m

Length = 43.32 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 + 12

We know that,

Perimeter = 2(length + breadth)

⇒ 2(2x + 12 + x) = 154 m

⇒ 2(3x + 12) = 154

⇒ 3x + 12 = 154/2

⇒ 3x = 77 – 12

⇒ 3x = 65

⇒ x = 65/3

⇒ x = 21.16 m

Therefore, Breadth = x = 21.16 cm

Length = 2x + 2

= (2 × 21.16) + 2

= 41.32 + 2

= 43.32 m
