### Area of a Parallelogram :

Area of a Parallelogram By: Sanny N. Tendilla### Parallelogram :

Parallelogram A parallelogram is a quadrilateral where the opposite sides are congruent and parallel. A rectangle is a type of parallelogram, but we often see parallelograms that are not rectangles (parallelograms without right angles).### Study the figure :

Study the figure Which sides have the same length? Side AC has the same length as side BD. Side AB has the same length as side CD. A B C D### Slide 4:

Area of a Parallelogram base height base Formula: A = b x h### How do we find the area of a parallelogram? :

How do we find the area of a parallelogram? Let's draw the figure in a graphing paper and cut. Put the cut part to the other side. What figure is now formed? How many square units are there in the rectangle? Parallelogram? A rectagle 15 sq units### Area of a Parallelogram :

Area of a Parallelogram Any side of a parallelogram can be considered a base. The height of a parallelogram is the perpendicular distance between opposite bases. The area formula is A=bh A=b x h A=5m x 3m A=15m2### Slide 7:

Area of a Parallelogram Height=8 cm Base=12 cm Formula: A = b x h### Slide 8:

A=12 cm x 8 cm Formula: A = b x h A= 96 cm² Area of a Parallelogram Base=12 cm Height=8 cm### Slide 9:

Find the area of the parallelogram Height = 6 in Base = 9 in Formula: A = b x h 9 in x 6 in A= 54 in² Answer### Slide 10:

How do we find the area of a parallelogram? Remember : To find the area of a parallelogram, use the formula A = b x h### Slide 11:
