Table Cover Square
URGENT. Hw not a very important question?
A tabletop is covered with tiles (the square). Each tile is 2 cm of the pictures are sides.Most white except for a red-tiled rectangular strip 4 cm from the edge insidefrom, PS table is rectangular, with width of 0.5 m in length and 1.5 m. actal is the question "How many red tiles are there? A) 180 B) 184 C) 368 D) 396
The number of 2cm "slots" throughout the width is 50 / 2 = 25 The number of 2cm "slots" throughout the length is 150 / 2 = 75 "4 cm from the edge" means that two rows of tiles are subtracted from each edge, so the number of red tiles in length is 75-4 = 71. The number of red tiles in the strip along the width is 25-4 = 21. The number of red tiles is 2 * 71 + 2 * 19 = 180 The number 19 is used to avoid counting the corners of the strip twice, that is, to be counted in length, and therefore should not be counted again in the width, so the number in the corner exclusive range is 21-2 = 19.
