4 x 9 = 36 (square feet).
21 x 4 = 84 square feet.
Four square meters is 43.06 square feet.
8 feet x 4 feet = 32 square feet (32 ft2)
Hi Your question doesn't make sense as it is written. To calculate square feet you need two dimensions. So 2 feet multiplied by 8 feet would give you 16 square feet. So would 4 feet multiplied by 4 feet. They are the same square footage, but different shapes. Think if you were adding a deck on your house and wanted to know how much paint to buy for it. If your deck is 10 feet by 16 feet, then 10 x 16 = 160 square feet. Then you look on the paint can and it says (conveniently) one can will cover 160 square feet. Phil
1000 square feet could look like a narrow road, 10 feet wide and 100 feet long. It could be a room 25 feet by 40 feet. It could be a piece of fabric 4 feet wide (48 inches) and 250 feet long.
4*9 = 36 square feet.4*9 = 36 square feet.4*9 = 36 square feet.4*9 = 36 square feet.
The answer is 4 feet by 4 feet or 4 x 4 = 16 square feet
21 x 4 = 84 square feet.
4 square yards is 36 square feet.
Well, let's paint a happy little picture here. To find the square footage of a rectangle, you simply multiply the length by the width. So, for a rectangle that is 4 feet by 10 feet, you would multiply 4 by 10 to get 40 square feet. Isn't that just a lovely little calculation?
4' * 4' = 16 sq feet.
20 feet x 4 feet = 80 square feet.
perfect square of 16= 4 because 4 times 4 is 16.
2' x 4' = 8 square feet.
4 x 9 = 36 (square feet).
36 x 4 = 144 square feet.
