Answer:
Area: [tex]9 cm^{2}[/tex]
Step-by-step explanation:
Since all sides of a square have equal lengths, the area of the square is [tex]a^{2}[/tex] (a = length of a side).
Since the length of the side of the square is given (is 3cm), the area of the square is [tex](3cm)^{2}[/tex] = [tex]9cm^{2}[/tex]
