8 square units and 
square units
Step-by-step explanation:
The area of the triangle ABC is 24 square units.
1. Triangles ABC and FBG are similar with scale factor 
then
2. Triangles ABC and DBE are similar with scale factor 
then
3. Thus, the area of the quadrilateral DFGE is
and the area of the quadrilateral ADEC is
Reflexive Property, the property where the quantity equals itself.
1119.15×12=13,429.8 deposits per year
cost of principal
PVAO=13,429.8×((1−(1+0.04)^(−15))÷(0.04))=149,317.72
interest
13,429.8×15−149,317.72=52,129.28
down payment
178,000×0.15=26,700
intagible tax
178,000×0.002=356
Total cost
52,129.28+356+149,317.72+26,700
=228,503....answer
