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.

Step-by-step explanation:
Answer:
a = 33
Step-by-step explanation:
IN a parallelogram consecutive angles are supplementary, thus
5a - 52 + 5a - 98 = 180, that is
10a - 150 = 180 ( add 150 to both sides )
10a = 330 ( divide both sides by 10 )
a = 33
The square root of 9800=
= 70 * square root of 2
