Let the side length of the square be x, then A = x^2
but diagonal (z) = sqrt(2x^2)
z^2 = 2x^2
x^2 = 1/2 z^2
Thus, A = 1/2 z^2
dA/dz = 1/2 (2z) = z
The rate of change is z.
When z = 4, the rate is 4.
2(-20)+3[5/4(-20)]
-40 + 3[-25]
-40 + -75
-115
-115 is your final answer.
I attached a pic with my work on it. Hope this helps!
