Answer:
19.5
Step-by-step explanation:
The area of a triangle given 3 coordinates can be solved using the formula:
Where
A_x is x coordinate of first point (here 7)
A_y is y coordinate of first point (here 1)
B_x is x coordinate of 2nd point (here 0)
B_y is y coordinate of 2nd point (here 10)
C_x is x coordinate of 3rd point (here 9)
C_y is y coordinate of 3rd point (here 4)
Plugging these into the formula, we get out answer:
Hence, the area is 19.5

Answer:
n = 1.5
Step-by-step explanation:
Given ratio of 1 : n is equivalent to the ratio 4 : 6.
We can rewrite these equivalent ratio as,
Now we have to solve this expression for the value of n.
n = 
n = 1.5
Therefore, n = 1.5 will be the answer.
