**Sarah**, Friday, December 10, 2010 at 4:58pmThe two sides equal 8.5 inches. The third side equals 14 inches.

8.5+8.5=17

17-3=14

14+17=31

**PsyDAG**, Saturday, December 11, 2010 at 10:00amLet x = length of each of the two sides. Then third side = 2x-3

2x + 2x -3 = 31

4x - 3 = 31

4x = 34

x = 8.5

2x - 3 = 17 -3 = 14
