Question

perimeter of a rectangular swimming pool is 154m. The length is 2m more than twice its breath. find the length and breath of the pool
​

Answer 1

Answer:

Step-by-step explanation:

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:

Step-by-step explanation:

P= 154m

breadth= x

length= 2+2x

P= 2(l+b)

   2(x+2+2x)= 154m

    2x + 4+4x = 154m

  6x +4= 154m

    6x= 154-4

    x= 150/6

x=25

length=2+2x = 2+ 2 x 25

                        52

Breadth= x= 25
