To find the length of Tristan's feet, we add 1/2 a foot to the length of Trey's feet. Without the exact length of Trey's feet, we cannot provide a numerical answer, but the relationship is based on basic arithmetic operations in mathematics.
The subject of this question is mathematics, specifically dealing with basic operations and measurements of length.
We can determine the length of Tristan's feet given the information about the length of his baby brother Trey's feet.
To calculate the length of Tristan's feet, we need to establish the length of Trey's feet first.
However, let's assume there is a typographical error, and we know Trey's feet are x feet long.
According to the statement, Tristan's feet are 1/2 a foot longer than Trey's.
Therefore, the length of Tristan's feet can be expressed as:
Tristan's feet length = Trey's feet length + 1/2
If Trey's feet are x feet long, then:
Tristan's feet length = x + 1/2
