A 72-inch diameter circle has an area of: 28.3 square feet.
Divide both sides by 12 to change to feet:- 8/12 times 16/12 = 8/9 square feet
The perimeter of a square is 100 inches. How many square tiles 1 inch on each edge are needed to cover its area?
perimeters will always be length so we have units of lenght such as mm, inch, feet etc. NOT area, so no square feet or square yards etc.
1070 square feet is 154080 square inches. (1 square foot is 12x12 or 144 square inches.)a 20x20 inch tile is 400 square inches.So the question could be restated as "how many 400 square inch tiles does it take to cover 154080 square inches?"154080 / 400 = 385.2
