1. Areas of Parallelograms and Trapezoids
Objective:
Learn to find the area of parallelograms and trapezoids.

2. To find the area of a parallelogram you must multiply the base times the height.
Formula:
Area = base × height or
A = b × h
Find the area of each parallelogram.
Example:
A = b x h
A = 8m x 6m
A = 48m2
YOUR EXAMPLE:

3. Area = (base 1 + base 2) × height
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.
Find the area for each trapezoid.
Formula:
Area = (base 1 + base 2) × height 2
A = (b1 + b2)h
Example :
A = (b1 + b2)h 2
A = (3m + 6m)4m
A = (9m)4m
A = 36m2
A = 18m2
