Question

6. Find the perimeter of a square whose area is 900 sq cm.​

Answer 1

$\huge {\tt {Perimetre of square = 4 × side}}$

So, perimeter of square whose area is 900 sq cm = 4 × 900 sq cm = 3600 sq cm

Answer 2

$\dag$

It is given that,

Area of square = 900 cm²

we know that,

Area of square = side ²

900 = 30²

so we get that,

one side of square =30 cm

and ,

perimeter of the square is 4 times side of square

so the perimeter will be

$4 \times 30$

$\bold{= \: 120}$

hence ,

the perimeter of the square is 120 CM
