Since the sides AB and CA are equal, we denote these sides by the letter x, and the side BC is 17 centimeters, and the perimeter is 62 centimeters, then we make the equation:
x + x + 17 = 62;
2x = 62 – 17;
2x = 45;
x = 22.5;
Therefore, the length of side AB is 22.5 centimeters.
Answer: 22.5 centimeters.
