Question

A rectangular piece of paper has area = 24 cm2 and length = 5 cm. Find its perimeter.​

Answer 1

Answer:

answer=breath×length

24= b×5

b= 24÷5

b= 4.8

perimeter= (l +b)×2

= (5+ 4.8)×2

19.6

Answer 2

Given ÷

Area of rectangle = 24cm²

Length = 5cm

________________

Concept to find out...

Perimeter of rectangle = ????

________________

Formula used ...

Perimeter = 2( l + b )

________________

Solution..

Area of rectangle = 24cm²

Area of rectangle = L x B

24cm ² = 5cm x B

$\frac{24c {m}^{2} }{5cm} = > 4.8cm$

Breadth = 4.8 cm

_________________

Perimeter of rectangle = 2(l + b )

perimeter of rectangle = 2 x ( 5cm + 4.8 cm )

Perimeter of rectangle = 2 x (9.8cm)

Perimeter of rectangle = 19.6cm
