Advanced MathEasySide of a tile from a combined area
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.
