Well, isn't that a lovely little question! To find the square footage of a rectangle, you simply multiply the length by the width. So, for a 15 feet by 30 feet space, you would have 450 square feet of room to create all sorts of beautiful things. Just imagine the happy little trees you could paint in that space!
30 square feet as 10 x 3 = 30
600 square feet
48 feet x 30 feet = 1440 square feet.
480 square feet.
30-ft x 20-ft = 600 square feet
570 square feet.
30 square meters = ~322.92 square feet.
30 feet x 30 feet = 900 square feet.
30 x 40 = 1200 square feet.
24 x 30 = 720 square feet.
30 acres = 1,306,800 square feet.
20' x 30' = 600 square feet.
30 inches by 10 feet = 25 square feet.
30 inches by 5 feet = 12.5 square feet.
30 feet x 30 feet = 900 square feet 900 square feet = 83.612736 square metres.
30 x 60 = 1800 square feet
There are 9 square feet in one square yard. Therefore, 30 square yards is equal to 30 x 9 = 270 square feet.
