(27) If the length​

Answer 1

Answer: (c.) 126 cm

Step-by-step explanation:

Perimeter of a rectangle = 2 ( l + b )

Area of rectangle = l × b

Given that, Area = 650 cm² and Breadth = 13 cm

⇒ Length × Breadth = Area

⇒ Length = Area / Breadth

⇒ Length = 650 / 13 = 50 cm

Hence Length is 50 cm.

⇒ Perimeter = 2 ( l + b )

⇒ Perimeter = 2 ( 50 + 13 )

⇒ Perimeter = 2 ( 63 )

⇒ Perimeter = 126 cm
