The net below represents a three-dimensional figure. The rectangles in the net are identical. The triangles are also identical. What is the surface area, in square inches (sq. in.), of the net?

A: 270

B: 282.75

C: 295.5

D: 321

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
