What is the formula for the area of a parallelogram?
Bonus: Are the formulas different, why or why not?
A = Base x Height
Yes the formulas are different. You cannot use the width of a parallelogram because the side length is not the same as the height of the shape.

Find the area of this shape:
Pink: 4 x 2 = 8ft x2
Blue: 3 x 2 = 6ft x2
Yellow: 4 x 3 = 12ft x2
16 + 12 + 24 = 52ft2
