Please answer the following question by reasoning step-by-step.
A monitor is 21 inches by 12 inches. There are 100 dots per inch. How many total pixels are there?

The display is 21 * 100 = 2100 pixels across.

The display is 12 * 100 = 1200 pixels tall.

That means there is a total of 2100 * 1200 = 2,520,000 pixels.

.

Therefore, the answer is 2520000
