A designer is working on a wooden puzzle that is in the shape of an equilateral triangle. He only has a total of 50 inches of wood to use, but he wants each side to be at least 12 inches. Which of the following is a possible choice for side lengths (s) of the puzzle?
4.5 Inches? 12+12=24 24+12=36 36+12=48 48+(.5 x 4)= 50 inches I'm not sure that is the correct answer, but it is what I would put. Sorry if that doesn't help.
