Explain this to me i don't understand it.

find the perimeter of the triangle formed in the coordinate plane by the following points:

x (0 ,2)
y (3,-2)
z (-7,-2)

what i have is d=v (3-0)^2 + (3-7)^2

the perimeter is 23.06

 round as needed.

 See attached picture:

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

i need the options
