the net of a triangular prism is shown below. use a ruler to measure the dimensions of the net to the nearest 1/4 inch which of the following is the closest to the lateral surface of the prism? A. 1.0 in. B. 6.25 in. C. 2.0 in. D. 5.25 in.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
