(side 1)² + (side 2)² = (diagonal)²
(9.5² + (14)² = (diagonal)²
90.25 + 196 = (diagonal)²
286.25 = (diagonal)²
√286.25 = √(diagonal)²
17 = diagonal
Answer: 17 inches
To round off to 10, the difference should range from 5 to 14. If the difference between two numbers is from 5 to 14, they all are rounded to 10.
Example:
(near to 10)
![26-15=11](https://tex.z-dn.net/?f=26-15%3D11)
![46-39=7](https://tex.z-dn.net/?f=46-39%3D7)
![50-42=8](https://tex.z-dn.net/?f=50-42%3D8)
11 is divisible by three three times with a remainder of two so the mixed number would be 3 2/3<span />
3 9/100 would be written as a decimal like this, 3.09. You say three and nine one hundredths. The 9 has to be in the hundredths place, so you put a 0 in front of it. And since the 3 is hole, you put it in front of the decimal point.
