The answer is D, (9,2)
This is because the distance between the segment is 12. We need a 3:1 ratio so when it is divided at 9, you have 9:3, which simplifies to 3:1.

Answer:

Area = 34.2cm^2

Step-by-step explanation:

Let the three sides be a, b and c respectively.

Such that:

a = 8

b = 9

c= 10

Required

Determine the area

This is calculated as:

Area = \sqrt{s(s-a)(s-b)(s-c)

Where

s = \frac{1}{2}(a + b + c)

Substitute values for a, b and c

s = \frac{1}{2}(8 + 9 + 10)

s = \frac{1}{2}(27)

s = 13.5

Substitute values for a, b, c and s in

Area = \sqrt{s(s-a)(s-b)(s-c)

Area = \sqrt{13.5 * (13.5 - 8)* (13.5 - 9)* (13.5 - 10)

Area = \sqrt{13.5 * 5.5* 4.5* 3.5

Area = \sqrt{1169.4375

Area = 34.2 -- Approximated
