Question

In a computer catalog, a computer monitor is listed as being 25 inches. If the height of the screen is 15 inches, what is the area of the screen to the nearest inch?

Answer 1

Answer: 20inch

Explanation:

Using the Pythagoras theorem:-

25^2 = 15^2 + x^2 where x = the width of the screen.

625 = 225 + x^2

x = √(625 - 225) = √400

= = 20 ins
