Q. A chessboard is one large square made up of 88 rows of 88 equal sized smaller squares. Krysta has two chessboards. On one board, the small squares are 22 inches by 22 inches. On the other, they are 33 inches by 33 inches. How much longer is the diagonal of the larger board than the diagonal of the smaller board? If necessary, round your answer to the nearest tenth.\newline____ inches
  1. Calculate side length: Calculate the side length of each chessboard. The smaller board has squares of 22 inches, so the side length is 8×2=168 \times 2 = 16 inches. The larger board has squares of 33 inches, so the side length is 8×3=248 \times 3 = 24 inches.
  2. Use Pythagorean theorem: Use the Pythagorean theorem to find the diagonal of each board. For the smaller board, diagonal = 162+162=256+256=512=22.6\sqrt{16^2 + 16^2} = \sqrt{256 + 256} = \sqrt{512} = 22.6 inches.
  3. Calculate diagonal: Calculate the diagonal for the larger board. Diagonal = 242+242=576+576=1152=33.9\sqrt{24^2 + 24^2} = \sqrt{576 + 576} = \sqrt{1152} = 33.9 inches.
  4. Find difference: Find the difference in the diagonals of the two boards. Difference = 33.933.9 inches - 22.622.6 inches = 11.311.3 inches.
