Question

If an image matrix has 360 rows and 360 columns, how many pixels are there in the image?

a. 21,600
b.129,600
c. 259,200
d.379,800

Answer 1

To find the number of pixels in an image with 360 rows and 360 columns, simply multiply these two values. Doing so gives us 129,600 pixels, which is the correct answer (option b).

Step-by-step explanation:

To determine the number of pixels in an image, you multiply the number of rows by the number of columns. Given an image matrix with 360 rows and 360 columns, the total number of pixels can be calculated by multiplying these two numbers together.

360 rows × 360 columns = 129,600 pixels

Therefore, the correct answer is option b. 129,600.
