Chapter 8 - Area

8.1 - Areas of Parallelograms and Rectangles

Objective Students will derive through discovery and investigation area formulas for rectangles and parallelograms

The area of a rectangle is the product of its base and height. A = bh

Area of a Parallelogram The area of a parallelogram is the product of a base and the corresponding height. h b A = bh

The base of a parallelogram is any of its sides. The corresponding altitude is a segment perpendicular to the line containing the base drawn to the side opposite the base. The height is the length of the altitude. h b h b

Find the area of the parallelogram.

Find the value of h in each parallelogram.

A diagonal divides any parallelogram into two congruent triangles.
