Question

the area of a rectangle is 63cm2.the lenght is 9cm calculate the perimeter of the rectangle​

Answer 1

Answer:

perimeter of rectangle = 32cm

Step-by-step explanation:

given,

area of rectangle = 63cm^2

length=9cm

area= l×b

63cm^2 = 9 × b

63/9=b

7 = b

Perimeter of rectangle = 2(l+b)

= 2(9+7)

= 2(16)

= 32cm

Answer 2

Answer :-

The perimeter of rectangle is 32cm².

Step-by-step explanation:

Given that,

• The area of rectangle = 63cm²
• The length of rectangle = 9cm

∴ The breadth of rectangle is :-

We know,

Area of rectangle = Length × Breadth,

⇒ Length × breadth = Area

⇒ 9 × breadth = 63

⇒ breadth = 63/9

⇒ breadth = 7cm.

According the question,

The perimeter of rectangle :-

We know,

Perimeter of rectangle = 2 ( l + b ),

Where,

• l = length
• b = Breadth

⇒ 2 ( l + b )

⇒ 2 ( 9 + 7 )

⇒ 2 ( 16 )

⇒ 32cm.

Hence, The perimeter of rectangle is 32cm.
