Question

The area of square sheet is 400cm^2. Find the side and perimeter of sheet​

Answer 1

Answer:

20,120

Step-by-step explanation:

side ^2 =400

side =root 400

side =20 cm

permimeter  =6x20

=120

Answer 2

Answer:

Given: Area of a square sheet = 400$cm^{2}$

To find: Side and perimeter of the sheet

Solution:

Area of a square = $(side)^{2}$

Side of the square = $\sqrt{side^{2}$

                               = $\sqrt{400cm^{2} }$

                               = 20cm

Therefore, side of the square sheet = 20cm

Perimeter of square = 4 * side

                                 = 4 * 20cm

                                 = 80cm

Therefore, perimeter of the square sheet = 80cm

Hence proved.
