The more precise your length and width are, the more precise your area <span>measurement will be. Take this as example:
</span>width = 9.3045 mm
<span>length = 8.023 mm
</span><span>
Let's first round up:
width = 9.3 mm
length = 8 mm
Area = 9.3*8 = 74.4 mm
But if you are more precise with the width and length:
</span>width = 9.3045 mm
<span>length = 8.023 mm
</span>Area = 9.3045 * 8.023 = <span>74.6500035 mm
The more precise your length and width are, the more precise your area is. Also, as you can see t</span>he more precise your length and width are, the more your area will increase and will be more accurate.<span>

ANSWER
12 inches
EXPLANATION
Let the length of the rectangular painting be inches, then the width will be inches.
Since the diagonal is the hypotenuse, we can apply the Pythagoras Theorem to find the length.
We expand to obtain;
We simplify to obtain a quadratic equation in .
We divide through by 2 to obtain.
We factor to obtain
Since we are dealing with length we discard the negative value.
Hence the length is 12 inches
