8.75 x 10 = 87.50, easiest way to figure out is divide each amount by each answer choice
You multiply 12 with the number in the column
B, F, and the third one I don’t know (I think it’s C)
For C you only listed two lengths. For D and E there is one length that is longer than the other two lengths combined, so it can’t make a triangle. Same thing for A except for A one length is the same as the other two lengths combined.
