The perimeter of a right triangle is 25 meters, and the area is 20 square meters. the lengths of the sides are each multiplied by 3. what is the area of the new triangle?me, not by just giving me the answer, but by explaining how i solve this so i can solve it on my own. : )

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.
