Answer 1

Answer:

18 cm

Step-by-step explanation:

breath of rectangle = 3 cm

according to question length = 2*3 cm

= 6 CM

perimeter of rectangle = 2(l+b)

= 2(6+3) cm

= 2*9 cm

= 18 cm

I hope it is useful for you.

Answer 2

Given:

✰ The length of the rectangular field is two times its breadth.

✰ Breadth of the rectangle = 3 cm

To find:

✠ The perimeter of the rectangle.

Solution:

Let's understand the concept first! As we are provided that the length of the rectangular field is two times its breadth that means we will multiply two by its breadth. We are given that the breadth of the rectangle is 3 cm, so 2 will be multiplied by 3 cm. After that by using the formula of perimeter of the rectangle. Putting the values in the formula and then doing the required calculations, we will find out the perimeter of rectangle.

Let's find out...✧

➛ Breadth of the rectangle = 3 cm

The length of the rectangular field is two times its breadth, therefore

➛ Length of the rectangle = ( 3 × 2 ) cm

➛ Length of the rectangle = 6 cm

The perimeter of a closed plane figure is the total length of its boundary.

✭ Perimeter of the rectangle = 2( l + b ) ✭

Where,

• l denotes the length of the rectangle.
• b denotes the breadth of the rectangle.

Putting the values in the formula, we have:

➤ Perimeter of the rectangle = 2( 6 + 3 )

➤ Perimeter of the rectangle = 2 × 9

➤ Perimeter of the rectangle = 18 cm

∴ The perimeter of the rectangle = 18 cm
