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

2. Formula for parallelogram:
To find the area of a parallelogram you must multiply the base times the height.
Find the area of each parallelogram.
Formula for parallelogram:
Area = base × height or
A = b × h
Example 1 :
A = b x h
A = 8m x 6m
A = 48 cm2

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