If the left side of the triangle is 12, and the right side is 2 cm longer, the right side is 12+2 = <<12+2=14>>14 cm long.

The sum of the left and right sides of the triangle is 14+12 = <<14+12=26>>26 cm.

If the sum of all sides of the is 50, and the left and right sides of the triangle are 26, the triangle base is 50-26 = <<50-26=24>>24 cm.
