To find the perimeter of a square using the area, we can follow the steps given below:
- Note down the area of square.
- Calculate the side length using the area. Side = √area
- Multiply this obtained value of side length, (√area) by 4 and express the answer in units. Perimeter = (√area) × 4 = 4√area units.

How do you find the perimiter of a square?
The perimeter of a square is the total length of all the sides of the square. Hence we can find the perimeter of a square by adding all its four sides. The perimeter of the given square is a + a + a + a. Since all sides of a square are equal, we only need one side to find its perimeter. a + a + a + a = 4 a units.
