A board has one corner square removed. Can the remaining squares be covered exactly by tiles?

Class 7Tiling PatternsGeometry
  • ANo, corners can never be covered
  • BNo, 15 squares is odd
  • CYes, with 8 tiles
  • DYes, with 7 tiles

Step-by-Step Solution

16 − 1 = 15 squares. Every tile covers 2 squares, so the total covered is always even. 15 is odd, so it is impossible.
Answer: B) No, 15 squares is odd
