Are you smart enough to figure this out?

Perimeter of the equilateral triangle ABC is 72 and the perimeter of the isosceles triangle DBC with the base BC is 50. Which is AB + BD?

    Since triangle ABC is equilateral, all sides are the same length. Therefore each side, including, of course, side BC, is 72/3 = 24. Side AB is also 24.

    Side BC forms the base of isoceles triangle DBC, which has a perimeter of 50. Since we know that side BC is 24, then the sum of sides BD and CD is 50 - 24 = 26. And since DBC is isoceles, then BD = CD = 26/2 = 13

    AB + BD = 24 + 13 = 37

    Yes, I am smart enough to figure this out as long as it's not a trick question. AB+BD is 37. Then again I might be wrong because this question is not phrased very well.
