• The perimeter of a rectanglar swimming pool is 154m. Its lenght is 2m more than twice its breadth. what are the length and the breadth of the pool.

• What are the length and the breadth of the pool.

$\qquad\qquad\underline{\textsf{\textbf{ \color{magenta}{Solution :-} }}}$

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

Henceforth, the length and the breadth of the pool is 52 m and 25 m respectively.

Answer 2

Step-by-step explanation:

Consider the Breadth as x

Length = 2x + 2

★ We know that :

Perimeter = 2(length + breadth)

⟹2(x+2x+2)=154

⟹2x+4x+4=154

⟹6x=154−4

⟹6x=150

⟹ x= 150/6

⟹x=25

Value of 2x + 2

⟹25×2+2

⟹50+2

⟹52

∴ The Length is 52 m and Breadth is 25 m.
