How many square tiles 6 inches on a side will be needed to cover this floor? (1 foot = 12 inches)? A) 40 B) 70 C) 120 D) 700 E) 1,200 E Source: Official Guide 2020 ### GMAT/MBA Expert GMAT Instructor Joined 04 Dec 2012 Posted: 2069 messages Followed by: 238 members Upvotes: 1443 If the scale is 1 in = 15 ft, then the dimensions of the floor = 15x20 ft. If each tile is 6 in x 6 in, that's 1/2 ft x 1/2 ft square. So every 1 sq feet of floor would take 4 tiles. 15 ft x 20 ft = 300 sq ft 300 sq ft x 4 tiles per sq ft = 1200 tiles total The answer is E. _________________ Ceilidh Erickson Manhattan Prep GMAT & GRE instructor EdM in Mind, Brain, and Education Harvard Graduate School of Education Manhattan Prep instructors all have 99th+ percentile scores and expert teaching experience.

Therefore, the area of the room is 15 x 20 = 300 sq. ft. Since each tile is 1/2 x 1/2 = 1/4 sq. ft, we need 300/(1/4) = 300 x 4 = 1,200 tiles to cover the floor of the room.
