The surface area of a 21 foot in ground pool is 346.36 square feet.
315
To find the surface are of the pool we need to make use of two formulae: 1) Circumference = pi x diameter and 2) area = pi x radius2. First: 21 = pi x D D = 6.68450761 So the radius = 6.68450761/2 = 3.342253805 Now: Area = pi x 3.3422538052 = 35.09366495 = 35 square feet (nearest whole number)
21*21 = 441 square feet.21*21 = 441 square feet.21*21 = 441 square feet.21*21 = 441 square feet.
My bedroom is 18 ft across and 21 long . What is the entire square footage of the room? I would like to replace the carpet and put new carpet and snap-on linoleum flooring tile... Any suggestions ?The room is gray and white?. Thank you, have a blessed day 😊🙏

294 square feet. Just multiply length by width - the answer is the square footage.
21 ft * 17 ft = 357 sq feet.

This question cannot be answered without more information. Does 21 foot refer to the length of a side of a square or rectangular pool, the radius or circumference of a circular pool? Is the pool of some other shape? What is its depth?
A floor measuring 32 feet by 13 feet covers an area of 416 square feet.
Diagonal of a square of side s is given by: d = 21/2s We have, d = 13 inches So, using the above formula we get, s = d/21/2 = 13/21/2 inches = 9.193 inches
273 square feet. Multiply length by width - the result is the area in square feet.
