Apackage of floor tiles contains 24 1 foot square tiles. find how many packages should be bought to cover a square ballroom floor whose side measures 66 feet

The number of 24, one square foot tiles required to cover a square floor whose side measures 66 ft will be given as follows:
Number of tiles required will be:
(Area of the floor)/(area of tiles)
Area of the floor is:
A=length*width
A=66*66=4356 ft²

Area of tiles=1 ft²

thus the number of tiles needed:
4356/1=4356 tiles

Given that 1 package has 24 tiles, the number of boxes required will be:
4356/24
=181.5
~182 packages
