You can't directly add feet, inches, and centimeters because they are different units of measurement. To get a single value, you need to convert everything to the same unit.

Here's how you can do it:

1. Convert everything to centimeters:

* 5 feet: 1 foot = 30.48 cm, so 5 feet = 5 * 30.48 cm = 152.4 cm

* 3 inches: 1 inch = 2.54 cm, so 3 inches = 3 * 2.54 cm = 7.62 cm

2. Add all the centimeters together:

* 152.4 cm + 7.62 cm + 3.5 cm = 163.52 cm

Therefore, 5 feet 3 inches and a half centimeter is equal to 163.52 centimeters.
