Wouldn't she need 40 times to run along the 10 ft side?

Wouldn't she need 60 tiles to run along the 15 ft side?

So what is 40 x 60 ?

or

area of floor = 150 square feet.

She will need 16 tiles for each square foot.

So .....

convert feet to inches:

10 feet = 120 inches

15 feet = 180 inches

get the area of the floor:

120in x 180in= 21,600in^2

divide the area of the floor to the area of the tile:

area of the tile is "9in^2"

21600in^2 divided by 9in^2 is 2,400 tiles.
