Without a second measurement of width, there is no way of knowing. Linear is length and square foot is area. You have to know length and width to figure it. 30 linear feet 1 foot wide would be 30 square feet.
30 feet x 20 feet = 600 square feet.
Well, isn't that just a lovely question! When you have a rectangle that is 30 feet long and 100 feet wide, you simply multiply those two numbers together to find the total square footage. So, in this case, 30 multiplied by 100 equals 3,000 square feet. Just imagine all the happy little trees you could fit in a space that big!
There is not enough information to answe. If approximately square it could be about 40 x 50, but a circular room of about 30 feet in diameter would have the same square footage.
Ah, isn't math a wonderful friend? To find the total square feet in a rectangle, you simply multiply the length by the width. So, for a 30 by 70 rectangle, you would multiply 30 by 70 to get 2,100 square feet. Just imagine all the happy little trees you could fit in that space!
Ah, what a lovely room you have there! To find the square footage, simply multiply the length by the width. In this case, 10 feet multiplied by 30 feet equals 300 square feet. Just imagine all the beautiful paintings and happy little plants you could fit in there!
105000 square feet
20 X 30 = 600 square feet.
900 square feet
30 feet x 20 feet = 600 square feet.
900 square feet
It is: 16*30 = 480 square feet
To find the square footage of a rectangular area, you multiply the length by the width. In this case, the area measuring 50 feet by 30 feet would have a square footage of 1,500 square feet (50 x 30 = 1,500).
30 feet by 28 feet equals 840 square feet. 30 inches by 28 inches equals 840 square inches, or 5.833 square feet.
To calculate the square footage of a 30x8 foot trailer, multiply the length by the width. So, 30 feet multiplied by 8 feet equals 240 square feet. Therefore, the square footage of the trailer is 240 square feet.
540
Multiply 9 times 30 to get 270 square feet.
Unfortunately, "It Depends" - - To determine square footage, you have to know whether the lawn is square, rectangular, circular, or some other shape. Assuming a rectangle (or square), the square footage is determined by multiplying the length by the width. Linear footage is determined by adding 2 times the length plus 2 times the width. If the lawn is a square, there is only one answer (as there is only one solution which will give 1500 square feet: length and width of 38.73-some odd decimal, meaning 2 times length and 2 times width gives a linear footage of some 154.92 feet). However, if the lawn is rectangular, there are an infinite number of answers. Giving three examples to show the range: 1) If the lawn is 50 feet long by 30 feet wide, that will give (50x30), or 1500 square feet of area and ([50x2]+[30x2]), or 160 linear feet. 2) If the lawn is 100 feet long by 15 feet wide, that will give (100x15), or 1500 square feet of area and ([100x2]+[15x2]), or 230 linear feet. 3) If the lawn is an alleyway in the middle of a big city and 1500 feet long by 1 foot wide, that will still give the required (1500x1), or 1500 square feet of area...but a whopping ([1500x2]+[1x2]), or 3002 linear feet around! (Note that the square gives the least linear footage possible for a rectangular-shaped lawn) Have fun figuring out circular, elliptoid, and other funny shaped lawns...
