The area of a triangle is given by the formula:

Area = (base × height) / 2

In this case, the area of triangle ABC is 35cm². Let's assume the base of the triangle is the side AC, and the height is the perpendicular distance from point B to side AC, which is y.

We can set up the equation:

35 = (AC × y) / 2

Since the diagram is not provided, we cannot determine the length of AC. However, we can express y in terms of AC:

y = (2 × 35) / AC
y = 70 / AC

Without knowing the length of AC, we cannot determine the exact value of y. However, if we assume that AC is a reasonable length (e.g., not extremely large or small), we can try to find a value of y that matches one of the answer choices.

Let's try to find a value of AC that makes y equal to one of the answer choices:

- If y = 5cm, then AC = 70 / 5 = 14cm (not a match)
- If y = 10cm, then AC = 70 / 10 = 7cm (not a match)
- If y = 17.5cm, then AC = 70 / 17.5 = 4cm (not a match)
- If y = 28cm, then AC = 70 / 28 = 2.5cm (not a match)
- If y = 70cm, then AC = 70 / 70 = 1cm (not a match)

However, if we try y = 7cm (not an answer choice), we get:

AC = 70 / 7 = 10cm

Now, if we try y = 10cm (answer choice B), we get:

AC = 70 / 10 = 7cm

This seems like a reasonable combination, so the correct answer might be:

B. 10cm
