The lengths of two sides of a triangle are 33 units and \(42\) units. The third side also has an integral length. What is the greatest possible number of units in the perimeter of the triangle?

Triangle side rule says the third side must be less than the sum of the other two sides

 

33 + 42 = 75     so side three must be < 75     side three = 74  ( integer length)   

 

74   + 33 + 42 = peimeter
