Using the formula, p = a + b +c, solve the following: the perimeter of a triangle is 48 inches. One side is 17 inches, and another is 14 inches. What is the length of the third side?

Answer 1

The perimeter of a triangle is the sum of it's three sides.

The problem tells you two of the sides are 14 and 17, and the sum of all three sides is 48.

So if the third side is X, then we have 14 + 17 + X = 48. Now solve for X.
