Question

If an equilateral triangle has a perimeter of 48, what is the length of the perpendicular bisector of any of its sides?Answers16$16\sqrt{3}$$8\sqrt{3}$8

Answer 1

Perimeter 48 → side length 48/3 = 16. The perpendicular bisector is the altitude of the equilateral triangle: h = 16·(√3)/2 = 8√3. Answer: 8√3.
