• `30sqrt3  cm^2`

• 356 cm²

Answer 1

The perimeter of a square is 72 cm, its area is 324 cm².

Explanation:

The side length of the square is found by dividing its perimeter by 4: \[\frac{72}{4} = 18\text{ cm}\]. The area of the square is then calculated as \[(\text{side})^2 = 18^2 = 324\text{ cm}^2\].
