Answer:
The maximum length of the umbrella should be 15"
Explanation:
We can actually visualize the umbrella and comparing it in terms of length with the box
So that for the umbrella to fit into the box it length must be equal or less than the length of the box
Given data
Length of box l=15"
Width of box w= 8"
The symbol " represents inches a unit for measuring le3
Hence the maximum length of umbrella that can fit into the box is the length of the box 15"
Anything more than 15" will not fit in.
