Question

Your family wants to purchase a new laptop with a 19" widescreen. Since the 19 inches represents the diagonal measurement of the screen (upper corner to lower corner), you want to find out the actual dimensions of the laptop. When you measured the laptop at the store, the height was 12 inches, but you don't remember the width. Calculate the width of the laptop to the nearest tenth of an inch.

16inches
17.2inches
