The perimeter of a square is 36ft. If you increase the length by 3ft and decrease the width by 5ft, what is the area of the new figure?

We can first get the side length for the square because a square has 4 sides of equal length.

4 x side length = 36 ft

side length = 9 ft

If you increase the length by 3 ft and decrease the width by 5 ft, we will get a 12 ft by 4 ft rectangle as a result.

length = 9 + 3 = 12 ft

width = 9 - 5 = 4 ft

The area of the rectangle is...

12 x 4 = 48 ft²

48 ft²

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.
