A rectangular tile measures 3 inches by 4 inches. What is the fewest number of these tiles that are needed to completely cover a
rectangular region that is 2 feet by 5 feet
1 answer:
1 foot = 12 inches.
Convert the dimensions of the region to inches:
2 feet = 24 inches
5 feet = 60 inches
Area of region = 24 x 60 = 1,440 sq. In.
Area of tile = 3 x 4 = 12 sq. In.
Number of tiles needed = 1440/12 = 120
120 tiles are needed.
