The size of a rectangular computer monitor is determined by the length of its diagonal. If a computer monitor has the length of 24 inches and the height of 18, what is the length of its diagonal to the nearest inch?

Answer 1

Using the Pythagorean theorem, we can find the length of the diagonal (d) of the rectangular computer monitor, given its length (l) and height (h):

d^2 = l^2 + h^2

Substituting the given values:

d^2 = 24^2 + 18^2
d^2 = 576 + 324
d^2 = 900

Taking the square root of both sides:

d ≈ √900
d ≈ 30

Therefore, the length of the diagonal is approximately 30 inches.
