The net below has identical triangles as bases. Which expression can be used to find the surface area of the figure represented by the net?

i think is g(1)=-1.

hope that i can

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )

what are the answer choices given for this problem?
