It is 20,000 square feet
Do you mean a square of side 200 ft? That would be 200 x 200 = 40,000 sq ft
100-ft x 200-ft = 20,000 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.
The dimensions could be 200 ft by 100 ft. or 400ft by 50 ft.
Knowing that the area of a circle is its radius squared times Pi, the area of a 10 ft radius circle is 100*Pi square ft, or about 314 square feet.
Do you mean a square of side 200 ft? That would be 200 x 200 = 40,000 sq ft
100 in * 100 in = 8.33... ft * 8.33... ft = 69.44... sq ft
100*150 = 15,000 sq ft
100-ft x 200-ft = 20,000 square feet
if you want the square footage, 15 ft x 20 ft is 300 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.
If you are looking for the square footage of the room, the height shouldn't make a difference. So the square footage would just be 10 ft x 10 ft = 100 square feet. If you are looking for surface area of all the walls, floor, and ceiling, that would be 100+100+80+80+80+80 = 520 square feet If you're looking for the cubic footage of the room, then you would use all three dimensions. 8ft x 10ft x 10ft = 800 cubic feet.
To calculate square footage, simply multiply the length by the width, so 10 ft by 5 ft would be 50 square feet.
Square footage of the room = 14 ft * 8 ft = 14*8 sq ft = 112 sq ft.
225 square ft.
Assuming that a 100 ft circle is one with a diameter of 100 ft (ie radius of 50 feet), area = pi*502 = 1963.5 sq feet
100 x 40 = 4000 sq ft (4000ft2).
