Help!!! --------------------- You have to find the length of the segment between each pair of points. Use the formula d = sqrt[(x1-x2)^2 + (y1-y2)^2] Example: distance from A to B d = sqrt[(10-6)^2 + (5-2)^2] = sqrt[16 + 9] = 5 -------------------------- After you find the three lengths, add them up; that is the perimeter. -------------------------- Comment: If you plot the points on an x/y coordinate system you will see the distances and the figure. =================================== Cheers, Stan H.
