Answer:
d = 9.84 m
Step-by-step explanation:
The dimensions of an envelope are 9 inches by 4 inches.
We need to find the maximum possible length of the pencil.
Let it be d. It can be calculated using Pythagoras theorem such that,
[tex]d=\sqrt{9^2+4^2} \\\\d=9.84\ m[/tex]
So, the maximum possible length of the pencil is 9.84 m./
