Need someone's help with the following question?
K Brown owns a large department building consisting of 200 units.

A triangle has the following properties:
1) It is scalene
2) It does not contain a right angle.
3) It has interger length sides
4) Its area is an integer.
Find the triangle with these properties which has the least perimeter.

[ Use Heron's Formula for the area of a triangle with sides a, b, c: where area = square root of s(s-a)(s-b)(s-c) where s is the semi perimeter (a+b+c)/2 ]

YOU HAVE A 16" CIRCLE,, AND YOU NEED TO MARK OUT 12 EQUALLY SPACED SPOTS ON THAT CIRCLE.... WHAT IS THE FORMULA FOR A STRAIGHT LINE LENGHT BETWEEN SPOTS? FOR THOSE WHO WANT TO GIVE ME THE CIRCUMFERENCE TRY PLOTTING THOSE POINTS ON THE CIRCLE WITH EITHER COMPASS OR RULER? THE CIRCUMFERENCE IS NOT WHAT I NEED!!! WHAT I DO NEED IS THE STRAIGHT LINE DISTANCE ACROSS THE ARC BETWEEN POINTS?
