Question

the area of a square sheet is 400 CM square find the side and perimeter of the sheet​

Answer 1

Answer:

Area of Square = 400cm^2

S × S = 400

S^2 = 400

S = √400

S = 20

Perimeter of Square = 4× S => 80cm

Answer 2

Area of square= Side× Side

So,

400 cm (sq.) = Area

√400 cm (sq.) = Side

20 cm. = Side

If side = 20 cm.

Area = 20 cm × 20 cm

= 400 cm (sq.)

Perimeter = 20 cm. × 4

= 80 cm.

Area= 400 cm (sq.)

Perimeter = 80 cm.
