Question

A television screen measures 18" tali by 24" wide. All televisions are advertised by giving the approximate length of the diagonal of the screen. (For example: A 48" television means that the diagonal of the television measures 48".) How should the television in this example be advertised?

Answer 1

30

Explanation:

Given that:

Dimension of TV = 18 by 24

Length of its diagonal :

Using Pythagoras :

Hypotenus = √(opposite² + adjacent²)

Hypotenus = Length of diagonal

Length of diagonal = √(18^2) + (24^2)

Length of diagonal = √900

Length of diagonal = 30
