A package 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
