Area is measured in "square" units. The area of a figure is the number of squares required to cover it completely, like tiles on a floor.
Area of a square = side times side. Since each side of a square is the same, it can simply be the length of one side squared.
Be sure to use the same units for all measurements. You cannot multiply feet times inches, it doesn't make a square measurement!
