Use Pythagorean theorem
18^2 + 24^2 = 900
root 900 and you will get 30in
30in is the answer.

Answer:

The length of its diagonal is 30 inches.

Explanation:

Since, the diagonal of a rectangle is,


d=√(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=√(24^2+18^2)


=√(576+324)


=√(900)


=30\text{ inches}
