Answer:

The length of its diagonal is 30 inches.

Step-by-step explanation:

Since, the diagonal of a rectangle is,

$d=\sqrt{l^2+w^2}$

Where, l is the length of the rectangle,

w is the width or height of the rectangle,

Here, l = 24 inches,

w = 18 inches,

Hence, length of the diagonal of the given computer monitor is,

$d=\sqrt{24^2+18^2}$

$=\sqrt{576+324}$

$=\sqrt{900}$

$=30\text{ inches}$
