4.5 cm ^ 2

Step-by-step explanation:

We have the following partial derivative, knowing that the area is A = x * y:

dA = (dpA / dpx) * dx + (dpA / dpy) * dy = y * dx + x * dy

and that | delta x | <= 0.1, | delta and | <= 0.1. We then use dx = 0.1 and dy = 0.1, with x = 50, y = 45;

So the maximum error in the area would be:

dA = y * dx + x * dy = 50 * 0.1 + 45 * 0.1 = 5 + 4.5 = 9.5

In other words, the maximum error is 4.5 cm ^ 2
