Perimeter Of The Rectangle

 

The perimeter is the total distance around the outside, which can be found by adding together the length of each side. In the case of a rectangle, opposite sides are equal in length, so the perimeter is twice its width plus twice its height.

Formula:

Perimeter = 2(l+w)

Where:

w is the width of the rectangle
l is the length of the rectangle

Demonstration:

Sonam wants to put a golden border all around a rectangular table cover  for the table shown in the figure.  The table is 4 m long and 2 m wide. Find the length of the golden border cloth required by Sonam.

Perimeter of the rectangle by formula

= 2 (l + w)

= 2 ( 4 + 2)

= 12 m
