Question

The area of a rectangle is 3.57 m square it's length is 2.1 .find its width also find peremiter of rectangle

Answer 1

Given:

• Area of a rectangle = 3.57 m²

• Length of rectangle, l = 2.1 m

To find out:

Find the width and Perimeter of rectangle?

Formula used:

• Area of rectangle = length × breadth

• Perimeter of rectangle = 2 ( l + b )

Solution:

Let the width be x

✪According to question:-

Area of rectangle = length × breadth

→ 3.57 = 2.1 × x

→ x = 3.57/21

→ x = 1.7

⋆ Width = x = 1.7 m

Now,

Perimeter of rectangle = 2 ( l + b )

= 2 ( 2.1 + 1.7 )

= 2 × 3.8

= 7.6 m

Hence, Width of rectangle is 1.7 m and perimeter of rectangle is 7.6 m.

Answer 2

Given:

The area of a rectangle is 3.57 m square it's length is 2.1 .

To find :

Find the width and Perimeter of rectangle?

Formula used:

★Area of rectangle = length × breadth

★Perimeter of rectangle = 2 ( l + b )

Solution:

Let the width be b

According to question,

Area of rectangle = length × breadth

➠3.57 = 2.1 × b

➠ b = 3.57/21

➠ b = 1.7

so, Width = 1.7 m

★ Perimeter of rectangle = 2 ( l + b )

= 2 ( 2.1 + 1.7 )

= 2 × 3.8

= 7.6 m

Finally, we got the perimeter of rectangle is 7.6 m
