Question

Laptop screen sizes are determined by the length of the diagonal portion of the screen, rounded to the nearest whole number. A laptop screen has a 12 inch width and the height measure 8 inches. Calculate the screen size.

Answer 1

14.42 or
`√(208)`

Explanation:

Use Pythagorean Theorem to solve:

`a^(2) +b^(2) = c^(2)`

`8^(2) +12^(2) = c^(2)`

`c^(2) = 208`

`c = √(208)` or 14.42
