Answer:
B
Step-by-step explanation:
It is a 379 page book so the answer is 379. That leaves B and D. It states she has already read 54 so that eliminates D leaving B. Now let's say we want more proof. It states 28 pages an hour. That means 28h. D doesn't have this either.
The area of the triangle can be calculated through the equation,
A = sqrt ((s)(s - a)(s - b)(s - c))
where A is area, s is the semiperimeter ((a + b + c)/2), a, b, and c are the sides given above.
The presented equation above is the Heron's formula.
Substituting the known values,
s = (8.7 + 10.1 + 9.8) / 2
s = 14.3
A = sqrt ((14.3)(14.3 - 8.7)(14.3 - 10.1)(14.3 - 9.8))
<em>A = 38.9 units squared
</em>Thus, the answer to this item is not among the choices. <em>
