Answer:
Area = 1/2 Base x height
Step-by-step explanation:
To find the area of a triangle, multiply the base of the height and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into two triangles.
x=7 y=3
-x+6y=11
2x-3y=5
-2x+12y=22
Add both equations
-2x+2x-3y+12=22+5
9y=27
y=3
plug y back in
-x+18=11
-x=-7
x=7
