Answer:
The height of parallelogram is 
Step-by-step explanation:
Area of parallelogram =
Area of parallelogram = 
Base of parallelogram = x+3
So, 

Hence The height of parallelogram is 
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
We have the following line:

The slope is 
By definition, if two lines are parallel then their slopes are equal. Thus, a line parallel to the given line will have a slope
Therefore, the equation of the parallel line will be of the form:

We substitute the given point and find "b":

Finally, the equation is:
