The area of a rectangle is the amount of space that is contained within the shape. It is calculated by the equation l x w
l represents the length (the vertical line)
w represents the width (the horizontal line)
Squares are very similar to rectangle, but their lengths and widths are the same, so you only need to know one side of a square to calculate its area. For example, if you are determining the area of a rectangle and the length is 3, the width is 6
Multiply the length by the width (3 x 6), which means the area is 18
