What is the area of this parallelogram

B. 12.25

Step-by-step explanation:

A=bxh=3.5·3.5=12.25

17.15

Step-by-step explanation:

There are 2 ways to solve this.

One way is this:

Add 1.4 and 3.5 together to get the total length of the parallelogram. The sum would be 4.9. Then multiply this number by the height of the figure(3.5cm). So that the product of 4.9 and 3.5 is 17.15.

The second way is this:

Find the area of the two triangles and the square and then add those products together. So add:

So solve this equation and you will get:

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.
