Question

the perimeter of the rectangle is a 20 CM if the length of the rectangle is 6 CM then its breadth will be e​

Answer 1

Given:

Perimeter of the rectangle = 20 cm

Length of the rectangle = 6 cm

Formula:

Perimeter of a rectangle = 2 ( Length + Breadth )

Assumption:

Let the breadth be b.

Explanation:

By putting the given values, we get

20 cm = 2 ( 6 cm + b )

or, 20/2 cm = 6 cm + b

or, 10 cm - 6 cm = b

or, 4 cm = b

Answer:

The breadth of the rectangle is 4 cm.

Answer 2

Answer:

4

Step-by-step explanation:

perimeter of rectangle = 20cm

length = 6cm

perimeter of rectangle = 2 ( l + b )

20 cm = 2 ( 6 cm + b )

20cm/2 = 6 cm + b

10cm = 6cm + b

b = 10cm - 6cm

b = 4 cm
