Answer 1

Answer:

41

Step-by-step explanation:

So basically you need to use the pythagorean thrm. Essentially, the diagonal and the width and length create a triangle, the diagonal being the hypothenuse. So the formula goes as $\sqrt[]{a^{2} +b^{2} }$. the variable "a" being the length and the variable "b" being the width.  So plug it in and there you have your answer!
