Answer:
d = 18.02 m
Step-by-step explanation:
Given that,
A rectangular lawn has a diagonal path running across it. The lawn is 10m wide and 15m long.
We need to find the length of the path.
The diagonal of a rectangle can be calculated as follows :
[tex]d=\sqrt{10^2+15^2} \\\\d=18.02\ m[/tex]
So, the length of the path is 18.02 m.
