She has 16 brownies

Step-by-step explanation:

Initially cut rectangular pan in to two halves.

Then cut each half in half again.

Now total pieces = 4

Now repeat cutting half on other side:

total pieces =8

Now divide each half into another half.

total pieces = 8 x 2 = 16

As can be shown in figure:

Black = first half

pink = dividing each half into another half.
