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?
[CLASS 8th NCERT CHAPTER 2 EX - 2.2; Q - 2]

Answer 1

Answer:

Let the breadth be 'x'

Length = 2 + 2x

Now perimeter of a rectangle = 2(l + b)

2(l + b) = 154

2 ( 2 + 2x + x) = 154

2 ( 2 + 3x) = 154

2 + 3x = 77

3x = 75

x = 25 m

Required breadth = 25 m

Length = 2 + 2 x 25 = 52 m

Hope This Helps You!

Answer 2

Answer:

Let the breath be 'x'

Then the Length = 2+2x

Perimeter of Rect. Pool = 2(l+b)

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

77. =. 3x +2

75. =. 3x

25. = x.

Breath = 25m

Length = 2x+2 = 52
