If the dimensions of the floor are 15+1/2 feet by 12 feet and the length of 1 square tile be 1/2 foot, then the number of tiles that is used to cover the floor is 744.
Given that the dimensions of the floor are 15+1/2 feet by 12 feet and the length of 1 square tile be 1/2 foot.
We required to find the number of tiles that can be used to cover the floor.
Firstly we need to find the area of the rectangular floor.
length of rectangular floor=15+1/2=31/2 feet
Breadth of rectangular floor=12 feet
Area=Length*Breadth
Area=31/2 *12
Area=186 
Side of 1 square tile=1/2 foot
Area of 1 square tile=1/2 *1/2
=1/4 
=1/4 
Number of tiles=Area of rectangular floor/Area of 1 tile
=186/1/4
=186*4
=744 tiles
Hence if the dimensions of the floor are 15+1/2 feet by 12 feet and the length of 1 square tile be 1/2 foot, then the number of tiles that is used to cover the floor is 744.
