If the area of a square is 361cm then the length of its side is

90,25 cm

Step-by-step explanation:

The sides of the square have all the same length.

So we can do like this:

length of the side: √361

length of the side: 90,25 cm

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
