Answer:
The area of the rectangle in polynomial form is 
Step-by-step explanation:
Given
Shape: Rectangle


Required
Area of the rectangle
The area of a rectangle is calculated as thus;

By substituting
for height and
for width; This gives

Expand the bracket

Open each bracket



Hence, the area of the rectangle in polynomial form is 
Slope of k=(3-2)/5-6
=-1
parallel lines have equal slopes
so slope of line parallel to k=-1
