Aim: How do we find the area of parallelograms, kites and trapezoids?

To find the area of a parallelogram is the same formula as finding the area of a rectangle:
Base times Height (b x h) = Area

• 

To find the area of a kite you must follow this formula:







(Diagonal 1 + Diagonal 2) / 2 = Area




To find the area of a trapezoid you must follow this formula:









(Base 1 + Base 2) /2  times Height = Area





Try these area problems:





If Diagonal 1 is 25 and Diagonal 2 is 30, what is the area of the kite?




If Base 1 is 6, Base 2 is 3 and the height is 8, What is the area of the trapezoid?




If the base is 7 and the height is 5 what is the area of the parallelogram?
