Question

In a computer catalog, a computer monitor is listed as being 27 inches. This distance is

the diagonal distance across the screen. If the screen measures 15 inches in height,
what is the actual width of the screen to the nearest inch?

Answer 1

The actual width of the screen = 22.45 inches

Explanation:

From the above question, we are given the following parameters

Diagonal = 27 inches

Height (Length) = 15 inches

Width = ???

To solve this question we would be using Pythagoras Theorem.

Diagonal² = Length² + Width²

Width² = Diagonal² - Length²

Width = √Diagonal² - Length²

Width = √27² - 15²

Width = √729 - 225

Width = √(504)

Width = 22.449944321 inches

Approximately to the nearest inch,

The actual width of the screen = 22.45 inches
