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.
