Elisa found a square digital image of a famous painting on a Website. The image contained 360,000 pixels. How many pixels tall was the image?

Answer 1

Hi Olivia,

Since the image was a dquare, you can assume that all the sides (s) would be the same measurement (here number of pixels). Then the area would be :

A = s²

360000 = s²

√¯360000 = s

600 pixels = s

The image would be 600 pixels tall.
