Question

5) The perimeter of a rectangle is 72 cm. If its length is 22 cm, find its breadth.​

Answer 1

Answer :

• Breadth of rectangle is 14cm.

Given :

• Perimeter of rectangle = 72cm
• Length of rectangle = 22cm

To find :

• Breadth of rectangle

Solution :

As we know that ,

• Perimeter of rectangle = 2(l + b)

Where , l is length 22cm , b is breadth and perimeter is 72cm

⇢ Perimeter of rectangle = 2(length + breadth)

⇢ 72 = 2(22 + b)

⇢ (22 + b) = 72/2

⇢ 22 + b = 36

⇢ b = 36 - 22

⇢ b = 14cm

Hence , Breadth of rectangle is 14cm.

Verification :

As we know that,

• Perimeter of rectangle = 2(l + b)

⇢ 2( length + breadth)

⇢ 2(22 + 14)

⇢ 2(36)

⇢ 72

Hence Verified

Answer 2

Step-by-step explanation:

Perimeter of rectangle = 2( l + b)

72 = 2( 22 + b)

72 = 44+b

72-44 = b

28 = b

The breadth of rectangular field = 28cm
