Question

If the area of a square is 324sq cm then its perimeter is?​

Answer 1

Answer:

72 cm

Step-by-step explanation:

Area of square = s × s

324 = s²

s² = 324

s = root 324

s = 18 cm

side of square = 18 cm

Perimeter of square = 4 × side

= 4 × 18

= 72 cm

Answer 2

$\huge\bold{\gray{\sf{Answer:}}}$

Explanation:

Given :

Area of a square is 324 sq.cm

To Find :

Perimeter of the square.

Formulas :

$\bold{\boxed{Area \: of \: a \: square = {(side)}^{2}}}$

$\bold{\boxed{Perimeter \:of \:a \:square =4a }}$

$= > {(side)}^{2} = 324$

$= > side = \sqrt{324} = 18$

Side of the square is 18cm

Now finding perimeter of the square:

$\bold{\red{ = > 4a}} = 4 \times 18 = {\bold{72m}}$
