Question

if the area of a square is 900cm , then it's perimeter will be
$900cm {}^{2}$
​

Answer 1

Step-by-step explanation:

Area of the square is 900cm²

so, actually the formula for area of square is Side(Side)

Side(Side) = 900cm²

Side² = 30² cm²

So, side of the square is 30cm

Now, the perimeter of the square is 4 times its side which is 4 x 30

= 120cm
