Question

Evaluate [r]; i.e., the units of r, in the expression
r =
squareroot of (s − a) (s − b) (s − c)
over s
,
where s =
1/2(a + b + c), and a, b, and c have
units of meters.

Answer 1

so.... what are the values for "a", "b" and "c"?

Answer 2

or do you have a triangle picture to show us?

yes I know is heron's formula \(\bf s = \cfrac{a+b+c}{2}\\
\sqrt{s(s-a)(s-b)(s-c)}\)

Answer 3

The question doesnt say the values

Answer 4

[r] = m
2. [r] = m1/3
3. [r] = 1
m
4. [r] = 1
m2
5. [r] = m3
6. [r] = 1
m1/3
7. [r] = m1/2

Answer 5

8. [r] = m2
9. [r] = 1
m1/2

Answer 6

hmm, Heron's formula is used to get the Area of a triangle when all you have is the sides only

Answer 7

can you take a screenshot of the material and post it here?
