Question

Which size would you see on the box for a new television whose screen measures 34.2 inches wide by 60.8 inches high ?

Answer 1

`70\ in`

Explanation:

we know that'

The box displays the diagonal measurement of a tv.

so

Applying the Pythagoras Theorem

Let

d -----> the diagonal of TV

`d^(2)=W^2+L^2`

substitute the given values

`d^(2)=34.2^2+60.8^(2)`

`d^(2)=4,866.28`

`d=69.8\ in`

Round to the nearest whole number

`d=70\ in`
