Parallelogram

what is a parallelograms?

A parallelograms is a quadrilateral with two pairs 

of opposite sides that are parallel

To find the area of a parallelogram, multiply the

base by the height. The formula is:
 
A = B * H where B is the base, H is the height, and * means multiply.


Example : Find the area of a parallelogram with a base of 7 inches and a height of 10 inches.
Solution:
A = B * H
A = (7 in) · (10 in)
A = 70 in²


perimeter = 2(w+h) 

 where:

w is the base length of the parallelogram

h is the side length



Example:
Find the perimeter of the parallelogram ABCD 
 
perimeter = 2 (w + h)
                = 2 (4+5)
                = 2 (9)
                = 18 cm
