The similarity ratio of two similar polygons is 7: 4. find the ratio of their areas

The ratio of their areas 49:16

Step-by-step explanation:

The similarity ratio is 7:4. Therefore, the scale factor is k = 7/4

The scale factor of the area k^2 = 7^2/4^2

= 49/16

Hence, the ratio of their areas 49:16

Hope this will helpful.

Thank you.

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.
