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

By using their formulas.

Parallelograms

How can we find the area of a parallelogram?

Well, one easy way is by using the formula.

The formula for a parallelogram is the same formula for a rectangle!!!!

Because if slice out one of the slanted edges of the parallelogram and put it togeether with the other side you get arectangle.

 Equals to area of


Recall: What was the formula for rectangles?
Base *hieght = Area

So if the parallelogram has a height of 7.6 in. and a base of 6in. the area is
going to be 45.6 cm cubed.

Try it on your own!!

What is the area of the parallelogram below?



Kites


\

Just follow these steps identify the d1  and d2.

Trapezoids

A trapezoid is a quadrilateral with on pair of parallel lines.

The formula for a trapezoid is the following;



AB =base 1 DC = base 2.

Area= height*base 1 + base2 / 2.
