(according to question the answer are given)(please choose your needed answer)

Step-by-step explanation:

perimeter of square = 4×side

= 1296 cm²

I HOPE YOU GOT YOUR ANSWER

PLEASE DON'T FORGET TO MARK ME AS BRAINLIEST

THEN I WILL FOLLOW YOU

• please check your question perimeter should be in only cm form not in cm²
• Or else the perimeter and area should interchange their place....then the answer will be as follows......⬇

Area of a square = (side)²

Then, side = √area

= √(441 cm²)

= 21 cm

Then, the perimeter of a square = 4×side

= 4×21 cm

= 84 cm
