Use the formula s2 to find the area of a square when s is equal to one side length of the square. Find the area of a square that has a side length of g mm.

To find the area of a square, we can use the formula:

s^2

where s is the side length of the square.

To find the area of a square with a side length of g mm, we substitute g for s:
g^2

Therefore, the area of a square with a side length of g mm is given by the formula g^2.
