A man runs 11 miles, turns and walks 9 miles, turns again and runs 6 miles returning to his starting point. What is the area of this triangle formed by his path?​

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
