Question

a rectangular piece of paper has area=24sq.cm and length=5 cm. find its perimeter​

Answer 1

Answer:

The Perimeter is 19.6 cm.

Step-by-step explanation:

Area of Rectangular Piece of Paper = L × B

= 5 × x

24 sq. cm = 5 × x

24 ÷ 5 = x

4.8 = x

Perimeter = 2 × ( L + B )

= 2 × ( 5 + 4.8 )

= 2 × 9.8

= 19.6 cm

Answer 2

Given:

• Area of paper = 24 sq. cm
• Length of paper = 5cm

To Find:

• Breadth = ?
• Perimeter = ?

Solution:

Here,area of rectangular paper is given 24 sq.cm and length is 5 cm and we have to find breadth and perimeter.

We know that,

$\large{\sf{\fbox{\green{Breadth = {\frac{Area}{Length}}}}}}$

Now,solve the question

$\: \: \sf \implies \: breadth = \frac{24}{5} = 4.8 \: cm$

Hence,Breadth of rectangular paper is 4.8cm

Now,we have to find Perimeter

We know that,

$\large{\sf{\fbox{\green{Perimeter= 2 (Length + Breadth)}}}}$

Now,solve the question

$\: \: \sf \implies \: perimeter = 2(5 + 4.8) \\ \\ \: \: \sf \implies \: perimeter = 2(9.8) \\ \\ \: \: \sf \implies \: perimeter = 19.6 \: cm$

Hence, Perimeter of the rectangular paper is 19.6cm.
