We are given:

Diagonal Length of the screen = 18 inches

Length of the screen = 7 inches

Width of the screen = x inches

Finding the width:

In the image, we notice a right-angle triangle

So, we can find x using the Pythagoras theorem

Using the Pythagoras theorem:

18² = 7² + x²

x² = 18² - 7²

x² = 324 - 49

x² = 275

x = 16.6

Hence, the screen is 16.6 inches wide

We are to find the width of the laptop

The width of the laptop is 16.6 inches

Diagonal length of the laptop = 18 inches

Length of the laptop = 7 inches

Width of the laptop = x inches

Using Pythagoras theorem

Diagonal ² = length ² + width ²

18² = 7² + x²

x² = 18² - 7²

x² = 324 - 49

x² = 275

find the square root of both sides

x = √275

x = 16.58

Approximately,

x = 16.6 inches
