Answer:
Step-by-step explanation:
the question states "Rating Factors" but may be better stated as Risk Factors. given that a 17 year-old male is a high driving risk factor (of 3.xx, i'm unable to see the image wording cause upon answering the image got smaller) and a 21 to 24 year old male has a risk factor of 2.15, i'm making the assumption on terminology that the "annual base premium" of $879 is multiplied by the risk factor of 2.15 to provide a total due amount of $1,889.85.
The square footage without the door and the window is 246
Angle Y is a right angle, so it’s 90 degrees. Angle W is 2x, since it’s opposite angles on a single line intersecting parallel lines. Triangles have 180 degrees, so adding up all sides creates the equation to solve:
X+Y+W=180
(3x-5)+90+2x=180
5x+85=180
5x=95
x=19
The perfect square 
can be expanded as follows:
So, we have to think of the term 
as 
, which implies 
.
Thus, we have to add 
, i.e. 16, to complete the perfect square:
