Answer 2

Answer :

• Perimeter of rectangle is 42cm

Given :

• Length of rectangle is 12.6cm
• Breadth of rectangle is 8.4cm

To find :

• Perimeter of rectangle

Solution :

Given,

• Length is 12.6cm
• Breadth is 8.4cm

We know that

• Perimeter of rectangle = 2(l + b)

Where,

• l is length of rectangle
• b is breadth of rectangle

↬ Perimeter of rectangle = 2(l + b)

↬ Perimeter of rectangle = 2(12.6 + 8.4)

↬ Perimeter of rectangle = 2(21)

↬ Perimeter of rectangle = 42cm

Hence,

Perimeter of rectangle is 42cm.
