Area of the 2 end triangles plus area of the 2 rectangular sides plus the area of the bottom rectangle
2 end Triangles
=2x(1/2bh)
=2x1/2x4x6
=24
2 side rectangles
=2(lw)
=2x5x13
=130
Bottom rectangle
=6x13
=78
Total = 24 + 130 + 78 =232
Y = 0.5x + 16.5
parallel so y = 0.5x + c
12 = 0.5 * -9 + c
12 = -4.5 + c
c = 16.5
y = 0.5x + 16.5
Mark brainliest please
X=9x-45/4
4x=36x-45
4x-36x=-45
-32x=-45
x=45/32
