Areas of Parallelograms and

TrapezoidsObjective: Learn to find the area of parallelograms and trapezoids.

To find the area of a parallelogram you must multiply the base times the height.

Find the area of each parallelogram. Formula:

Area = base × height or A = b × h

Example 1 :

Example 2:

To find the area of a trapezoid you have to add the two bases, multiply by the height, and the result divide it by two.

Formula:

Area = (base 1 + base 2) × height

2

A = (b1 + b2)h 2

Find the area for each trapezoid. Example 1:
