Question

The perimeter of a rectangle swimming pools is 154 metre its length is 2 metre more than twice its breath what are the length and the breath of the swimming pool​

Answer 1

Given :

The perimeter of rectangle swimming pools is 154 m. Length is 2 m more than twice the breadth.

To find :

Length & breadth of swimming pool.

Solution :

Let the breadth of swimming pool be b m.

⇒ Length of swimming pool = 2b + 2

As we know,

☛ Perimeter of rectangle = 2(l + b)

Putting all values :

⇒ 154 = 2(2b + 2 + b)

⇒ 154/2 = 3b + 2

⇒ 77 = 3b + 2

⇒ 77 - 2 = 3b

⇒ 75 = 3b

⇒ b = 75/3

⇒ b = 25

★ Dimensions of rectangle :

⇒ Length = 2b + 2

= 2(25) + 2

= 50 + 2

= 52 m

⇒Breadth = b

= 25 m

Therefore,

Length & breadth of swimming pool are 52 m & 25 m respectively.

Answer 2

Step-by-step explanation:

Given that:

• Perimeter = 154 m
• Length is 2m more than twice its breadth

To Find :

• Length
• Breadth

Solution :

Let Breadth of rectangular swimming pool= x

Length = 2x + 2

——--—--——————————-——

Perimeter = 2( length +Breadth)

—-------------------------------------------

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

=> 154 = 2( 3x+2)

=> 154 =6x + 4

=> 154 - 4 = 6x

=> 150 = 6x

=> 150/6 = x

=> 25 = x

=> x = 25 m

Breadth (x) = 25 m

Length = 2x +2

= 2×25 + 2

= 50 + 2

= 52 m Ans.
