The document discusses calculating area for different shapes such as rectangles, squares, and triangles. It provides the formulas for finding the area of each shape: the area of a rectangle is length times width, the area of a square is the side squared, and the area of a triangle is one-half the base times the height. The document also mentions that area is used to determine the amount of materials needed for projects and includes a worksheet for practice calculating areas.
