Answer:
420
Step-by-step explanation:
7 * 3 = 21
21 * 2 = 42
42 * 10 = 420
7 * 3 * 2 * 10 = 420
<u>The area is 420</u>
Since density is the ratio of mass to (in this case) area, we can find the mass of the triangular region
by computing the double integral of the density function over
:

The boundary of
is determined by a set of lines in the
plane. One way to describe the region
is by the set of points,

So the mass is
