Answer:
d. 690.1 units²
Step-by-step explanation:
1. You can use the Heron's formula to calculate the area of the triangle, which is:
Where:
2. Calculate 
:
3. Substitute values into the formula shown above and calculate the area, as following:
4. Therefore, the area is 690.1 units².
8/20 is greater than 2/10. If you were to make the denominators the same, by mulipling 2x2 and 10x2, you would get 4/20, which is less than 8/20.
It depends on which triangle it actually is
