2 x (L + W) = Perimeter
2(L + 16) = 80 Then divide both sides by 2
L + 16 = 40 Then subtract 16 from both sides
L = 24 feet
Answer:
To get the slope (which we'll call n) of a line perpendicular to another line with slope (a/b), use

Then we just plug in the point we want to cross and solve for the constant.
Step-by-step explanation:
we see that m = 
so, 
now we have the equation

plugging in (6, -4) we get

This gives us our function
