Answer:
Area = 126
Step-by-step explanation:
To figure out the area of the triangle, we must do 1/2 base times height. Which would be 1/2 of 6 times 6. Which is 18. Then to figure out the rectangle is just doing the width times the length and the same for the square. So 6 times 12 plus 6 times 6 equals 108. Then we add the triangles area and we come out with 108 plus 18 which equals 126.

2)
a) elimination method
b) substitution method
c) substitution method
For the first part we can elimate the y variable by subtracting the equations. We can then find the value of x.
For the second part we can substitute y as 2x+5 in the second equation and solve for x.
For the third part we can substitute y as 4x+3 in the first equation and solve for x.
