Question

Find the area and perimeter of a square whose side =20cm​

Answer 1

Answer:

Given,

Side of a square = 20cm

Area of the square = side × side= 20 cm × 20 cm = 400cm^2

Perimeter of square = 4×side = 4×20cm = 80cm

Answer 2

Given,

Side of the square = 20 cm

To find,

We have to find the area and perimeter of the square.

Solution,

The area and perimeter of the square are 400cm² and 80cm respectively.

We can simply find the area of the square and perimeter by using their formulas.

              Area of square = (side)²

                                        = 20 * 20

                                        = 400 cm²

Perimeter of the square = 4 * side

                                       = 4 * 20

                                       = 80 cm

Hence, the area and the perimeter of the square whose side is 20 cm are 400cm² and 80 cm respectively.
