The parametric equations of the line are:
and 
To find the area of an obtuse triangle you have to multiply the base of the triangle by the vertical height and divide the result by 2 following the formula:

The base of the triangle is b= 7 miles and the height is h= 8 miles, using these lengths calculate the area as follows:

The area of the triangle is 28 square miles.
Answer:
It is not proportional
Step-by-step explanation:
To figure out if something is proportional they have to equal the same thing.
As you can see on the problem 0.2 and 0.2 are the same thing, and since one is on the numerator and one is on the demoninator those two can cross out.
Now we come to the 0.08 and the 0.8.
They are not the same thing the 0.08 has an extra 0.
So this is not proportional
