2 ft x 4ft = 8ft²
4 by 7 feet is 28 square feet.

It is 4 times 15 = 60 square feet
40 square feet. Multiply length by width to get square feet.
2 ft x 4ft = 8ft²
It is: 2 feet times 2 feet = 4 square feet
For square footage (area) you only have two measurements. So a carpet 4 ft x 4 ft has a square footage of 16 square feet. And a carpet of 4 ft x 8 ft has a square footage of 32 square feet. Three measurements like 4 ft x 4 ft x 8 ft give you cubic footage, or volume. So the volume of a container that size would be 128 cubic feet.
4 by 7 feet is 28 square feet.
You have to multiply the two dimensions to get the area. In this case the answer will be 8 square feet.

Typically they are 2000 - 3000 square feet.
If you mean 4 feet in diameter then the area is 4pi sqinches ie 4/2 x 4/2 x pi
You multiply them together - 20 x 4 = 80 square feet
It is 4 times 15 = 60 square feet
Square footage is a measure of area in 2 dimensional space. there are three numbers given and so is not a 2-d object.
To get the square footage you simply multiply the lengths of the sides together (ie here 4*6 which comes to 24 ) - so the square footage is 24 square feet.
