Answer: The diagonal length would be 16.40122
Step-by-step explanation:
1. Get your length and width measurements.
2. Use the equation [tex]\sqrt{w^{2} +l^{2}[/tex] which in this case would be [tex]\sqrt{10^{2} +13^{2}[/tex] which when simplifying the square root you get the answer of 16.4 or 16.40122 to be exact.
