Answer:
Step-by-step explanation:
area of top=7×6=42 yd²
area of bottom=3×6=18 yd²
area of two rectangles=2[4×6]=48 yd²
area of two trapezoids=2[1/2(7+3)×3.5]=35 yd²
total surface area=42+18+48+35=143 yd²
The slope of CD is

The slope of the perpendicular bisector is the negative reciprocal,

The perpendicular bisector passes through M, the midpoint of CD
M =( (0+2)/2, (-4 + 6)/2) = (1, -1)
So point slope form for the perpendicular bisector is

Solving for y gives slope intercept form.

Not sure how to type that without spaces; we didn't have online homework back then.
Answer: y=(-1/5)x-4/5
