It is given that,

It is also given that, d = 12.1 inches, w = 9.6 inches, putting the values we get,

So the height of the laptop is 7.4 inches.

Answer 2

D. 7.4 inches

Explanation:

We can use pyhtagoras theorem to calculate the height of the laptop screen.

It is given that,

`d=√(w^2+h^2)`

`d^2=w^2+h^2`

It is also given that, d = 12.1 inches, w = 9.6 inches, putting the values we get,

`(12.1)^2=(9.6)^2+h^2`

`146.41=92.16+h^2`

`h^2=146.41-92.16`

`h^2=49.25`

`h=7.017`

So the height of the laptop is 7.4 inches.
