Answer 1

Step-by-step explanation:

${\huge{\boxed{\sf{\pink{☞Answe࿐★}}}}}$

Given :-

Perimeter of rectangular swimming pool = 154 m Let the breadth of rectangle be = x

According to the question,

Length of the rectangle = 2x + 2

Perimeter = 2(l + b)

⇒ 2(2x + 2 + x) = 154 m

⇒ 2(3x + 2) = 154

⇒ 3x +2 = 154/2

⇒ 3x = 77 – 2

⇒ 3x = 75

⇒ x = 75/3

⇒ x = 25 m

Therefore, Breadth = x = 25 cm

Length = 2x + 2

= (2 × 25) + 2

= 50 + 2

= 52 m

Answer 2

Answer:

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

= 2( 154+2)

= 2x 156

= 312
