What is the length of each side of a square if it has an area of 9yd squared

3 yds.

Step-by-step explanation:

That would be the square root of 9 which is 3.

3 yd * 3 yd = 9 yd,

All 4 sides of a square are equal in length and the area = one side * the attached side.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
