How to measure the area of a parallelogram




remember to measure base x height (not base x side)







base x height

8 cm





8 cm

8 x 8 = 64

you can also divide the parallelogram into two triangles as shown to the left


( go to triangles on website to find how to measure area of triangles )

how to measure the area of a trapazoid

how to measure the area of a trapazoid








to measure the area of a trapazoid, you must calculate the top of the trapazoid and the bottom.





then multiply that number by half of the height
height = 4 cm so 4 divided by 2 = 2 so 6 x 2 = 12








you can also divide it into two triangles (go to triangles to find out how to find the area of a triangle)

Base times Hight is the formula for triangle! 

b*h=Formula for triangle!

Area of a triangle
A=1/2 BH
Base times Height
Multiply the base
And the hieght Divade by two
