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.
The unit rate is $2.75
If you divide the cost by Movies/week you would always get $2.75
For example:
11÷4=2.75
13.75÷5=2.75
19.25÷7=2.75
22÷8=2.75
Hope this helps you :))
