Answer:
3cm
Step-by-step explanation:
The shape of an iPod Shuffle is similar to that of square.
The Area of a square = (Side length)²
We are told in the question that the area of the iPod was 9 cm².
We are to find the side length of the iPod.
Therefore,
The Area of a square = (Side length)²
9cm² = L²
Square root both sides
√9 cm² = √L²
L = 3cm
Therefore, the side of the iPod is 3cm long.
