Question

Three identical squares have side lengths of x units. Which formula can be used to find A, the total area of all three squares?

Answer 1

Each square has an area given by its side length squared, so the area of one square is given by x². Since the three squares are identical, each of their areas is the same (x²). So we can just add the areas together to get the total, A: x²+x²+x² = 3x².
