Area of a rectangle specifies an area in the coordinate space that is enclosed by the rectangular object. To find the area of a rectangle, multiply the length and the width. Area is usually measured in square units such as square inches, square feet or square meters.In the above figure, the length of the rectangle is "l" and the width of the rectangle is "w". Therefore, the area of the rectangle formula is (l X w) square units.

Applet contains a modifiable parallelogram that students can transform into another familiar figure (rectangle.) Since the area of the rectangle is the same as the area of the original parallelogram, students can then more readily see that the formula for the area of any parallelogram is Area of a Parallelogram = (Base Area)(True Height).
