Answer:
I can't currently fully answer, hoping someone can come along and help-
Step-by-step explanation:
separate the shape into 3 triangles and 1 rectangle and then add all the areas together
area of a triangle is 1/2 base times height and area of a rectangle is length multiplied by width
1 1 1 2
2 -3 1 -11 -2R1 + R2 → R2
-1 2 -1 8 R1 + R3 → R3
1 1 1 2
0 -5 -1 -15 R2 ⇔ R3
0 3 0 10
1 1 1 2
0 3 0 10 -R3
0 -5 -1 -15
1 1 1 2
0 3 0 10 1/3 R2
0 5 1 15
1 1 1 2 -R2 + R1
0 1 0 10/3 -5R2 + R3
0 5 1 15
1 0 1 -4/3
0 1 0 10/3 -R3 + R1
0 0 1 -5/3
1 0 0 1/3
0 1 0 10/3
0 0 1 -5/3
Therefore, x = 1/3, y = 10/3, z = -5/3
1/3b = 4/5
Do the cross multiplication
1(5) = 3b(4)
5=12b
