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.

Nets and Composite Figures. In this collaborative activity, students find the areas of nets (rectangular prisms, triangular prisms, square pyramids, triangular pyramids) and composite figures that are made of rectangles and triangles. There is no need to know the formula for the area of a trapezoid to compute any of the areas.

This 4 page lesson includes a page that details the formulas for finding the area of a square, rectangle, triangle, parallelogram and trapezoid. The second and third pages are practice problems. Answer Keys included!
