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 8/15 mm.

The formula to find the area of a square is:

Area of square = side length^2

In this case, the side length of the square is 8/15 mm.
Therefore, substituting the value of s into the formula, we have:

Area of square = (8/15 mm)^2

To simplify this expression, we square the numerator and the denominator separately:

Area of square = (64/225) mm^2

Hence, the area of the square with a side length of 8/15 mm is 64/225 square millimeters.
