**Henry**, Monday, October 4, 2010 at 7:39pmSince CD is BOTH the median and altitude, the triangle is isosceles

and AB is the short side. The 2 long

sides(AB and BC) are equal.

AB = BC,

2X + 8 = 3X + 5,

2X - 3X = 5 - 8,

-X = -3,

X = 3.

P = AB + AC + BC,

P = (5X + 3) + (2X + 8) + (3X + 5),

P = (5*3 + 3) + (2*3 + 8) + (3*3 + 5),

P = 18 + 14 + 14 = 46.
