Advanced Math practice question

Three identical square tiles have a combined area of 48 square inches. What is the side length, in inches, of one tile?

Answer: 4

If a side is s, then 3s² = 48, so s² = 16 and s = 4.

Common wrong answers

If you answered 8
8 halves 16 instead of taking its square root.
If you answered 16
16 is the AREA of one tile, not its side.
If you answered 6.93
6.93 is √48, treating all three tiles as one square.
