Area of Parallelograms #36

A polygon is a closed figure formed by 3 or more straight lines. VOCABULARY A polygon is a closed figure formed by 3 or more straight lines. A parallelogram is a quadrilateral with opposite sides parallel and opposite sides the same length. A rhombus is a parallelogram with four equal sides. The area of a parallelogram (A=bh) is the product of its base b and its height h. The base of a parallelogram can be any one of its sides. The height of the parallelogram is the perpendicular distance from the base to the opposite side. A formula is an equation that shows a relationship among certain quantities.

The area of a parallelogram = bh. The area of a rectangle = lw. FYI You can use the formula for the area of a rectangle to write a formula for the area of a parallelogram. Imagine cutting off the triangle drawn in the parallelogram and sliding it to the right to form a rectangle. The area of a parallelogram = bh. The area of a rectangle = lw. The base of the parallelogram is the length of the rectangle. The height of the parallelogram is the width of the rectangle.
