Neither because the square root of 400 is 20
No, it is neither.
21.447610589527216 (does not repeat to 20 places)
What you are asking is, "What is the square root of 20?" The answer to 9 decimal places is 4.472135955
Each side of the square is 20 inches and by using Pythagoras' theorem its diagonal is 20 times the square root of 2 which is about 28.284 inches rounded to 3 decimal places.
A decimal approx. - rounded to 2 decimal places would be 6.47 In root notation, however, this can be simplified to 2 + 2√5
Expressed as a surd, sqrt(372000) = 20 sqrt(930). Expressed as a decimal, rounded to five decimal places, this is equal to 609.91803.
Neither because the square root of 400 is 20
No, it is neither.
Expressed as a surd, sqrt(800) = 20 sqrt(2). Expressed as a decimal, rounded to two decimal places, sqrt(800) = ±28.28.

Each side of the square is 20 inches and by using Pythagoras' theorem its diagonal is 20 times the square root of 2 which is about 28.284 inches rounded to 3 decimal places.
Using Pythagoras' theorem it works out as 20 times the square root of 5 which is about 44.721 feet to three decimal places.
sqrt(16) + 4 = 4 + 4 = 8sqrt(16 + 4) = sqrt(20) = 4.47 (to two decimal places)
Expressed as a surd in its simplest form, 5 sqrt(48) is equal to 20 sqrt(3). Expressed as a decimal, and rounded to two decimal places, this is equal to 34.64.
sqrt(20)= 4.472135955At nine places and looking very irrational to me!
