Question

The perimeter of rectangular of an area 650cm² , whose breath is 13cm, is​

Answer 1

Answer:

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

This is the required answer.

Answer 2

Answer:

126 cm

Step-by-step explanation:

the area of rectangle = 650cm2

breadth = 13cm

area of rectangle =( length × breadth)

650=(length × 13)

length = 650÷ 13

length = 50 cm

perimeter = 2(length +breadth)

2(50+ 13)

2× 63

126cm
