Area is the number of square units inside a polygon.
To find the area of a rectangle, multiply the length by the width. The formula is: a=lw, where a is the area, l is the length, and w is the width.
A square is a rectangle with 4 equal sides. To find the area of a square, multiply the length of one side by itself. The formula is: a=s2 where a is the area, s is the length of a side, and 2 means square the side length.
