**Perimeter of Square**

Total covering or outer length of a closed plane figure is
called the perimeter of the figure. A square is a quadrilateral or a four sided
plane figure having its all sides equal and each angle 90°. Therefore the sum
of the lengths of all four sides of a square is the

**perimeter of square**.
In a square, all four sides are equal and the measure of the
side is taken as the length(l) of the square. In the given figure; ABCD is a square
and AB, BC, CD and AD are its four equal sides.

Length of the square ABCD = AB = BC = CD = AD = l

Perimeter of the square ABCD = AB+BC+CD+AD

= l + l + l + l

= 4l

Hence the perimeter of the square is given by the formula:

*Perimeter = 4l*

Also, the length of diagonal of the square is given by

*Workout Examples*

*Example 1: Find the perimeter of the given plane figure.*

*Solution: Here,*

*The given figure is a square of length (l) = 8cm*

*∴*

*Perimeter = 4l*

*= 4 × 8cm*

*= 32cm*

*Example 2: A square garden is 35m long, calculate: (a) Perimeter of the garden. (b) The length of the rope required to surround it to 5 times.*

*Solution: Here,*

*The length of the square garden (l) = 35cm*

*∴*

*Perimeter of the garden = 4l*

*= 4 × 35m*

*= 140cm*

*Length of rope required to surround 5 times = 5 × perimeter of garden*

*= 5 × 140m*

*= 700m*
