Answer 1

Answer :

• Perimeter of rectangle is 40cm

Given :

• Length of rectangle is 8cm
• Breadth of rectangle is 12cm

To find :

• Perimeter of rectangle

Solution :

As we know that,

• Perimeter of rectangle = 2(l + b)

Where, l is length and b is breadth

》Perimeter of rectangle = 2(length+ breadth)

》2(8 + 12)

》2(20)

》40cm

Hence , Perimeter of rectangle is 40cm

Verification :

• Length of rectangle is 8cm
• Breadth of rectangle is 12cm
• Perimeter of rectangle is 40cm

We know that,

• Perimeter of rectangle = 2(l + b)

》40 = 2(8 + 12)

》40 = 2(20)

》40 = 40

Hence Verified
