11.2 Area of Parallelograms and Triangles Students will be able to find the area of parallelograms and triangles given varied information.

Partner work Cut out the parallelogram you were given. Follow the directions and determine the formula for the area of a parallelogram. Do the same for the triangles.

Area of a parallelogram…why?why A=bh h b

Area of a triangle h b h b

Example 1 Find the area of the parallelogram.

Example 2 Find the altitude of a parallelogram with base 12 cm and area 96 square cm.

Example 3 In a parallelogram, the base and the altitude are in a ratio of 10:7. If the area of the parallelogram is 1120 square meters, find the length of the base and altitude.

Example 4 Find the area of an isosceles right triangle with hypotenuse cm.

Example 5 Find the area of an isosceles triangle with side lengths 10, 10 and 16.
