Let
 
          
using a graphing tool 
see the attached figure to better understand the problem
we know that
 Parallelogram is a quadrilateral with opposite sides parallel and equal in length
so

The area of a parallelogram is equal to
 
   
where 
B is the base
h is the height 
the base B is equal to the distance AB
the height h is equal to the distance AE 
Step 1
<u>Find the distance AB</u>
the formula to calculate the distance between two points is equal to

 
      
substitute the values



Step 2
<u>Find the distance AE</u>
the formula to calculate the distance between two points is equal to

 
      
substitute the values



Step 3
<u>Find the area of the parallelogram</u>
The area of a parallelogram is equal to


substitute the values

therefore
<u>the answer is</u>
the area of the parallelogram is
