Question

What is the length of the diagonal of a square monitor that is 16 inches wide and 16 inches high?

Answer 1

22.63 inches

Explanation:

Length of the square monitor = 16 inches

Width of the square monitor = 16 inches

Let the diagonal of the monitor = l inches

Then the square of the diagonal is given by sum of the squares of length and width.

`\[l^(2)=16^(2)+16^(2)\]`

`\[=> l^(2)=256+256\]`

`\[=> l^(2)=512\]`

`\[=> l=√(512)\]`

`\[=> l=22.63\]`

Hence the length of the diagonal is 22.63 inches.
