Man with the mission. The correct answer for #14) is C and not B. Even i got 9.something and marked B. If u want the proof,,,,,,,,,,,,i will upload the image.
Also in #15) if we take a b c as -3 -2 -1 then shouldnt abc=(-3*-2*-1)=-6
In #16) Shouldnt 13 been considered twice since it is the top as well as base of the rect (along being hypo of the triangle)??
so Perimeter=13+13+12+5+17+17=77??
I may be wrong. Please explain
