Answer:
The correct option is B.
Step-by-step explanation:
Given: Rectangle with the stake marking where diagonal intersect each other.
To find : The length of the one of the diagonal.
Solution:
Diagonals of rectangle bisect each other into two equal parts.
So, the distance of all vertices from the stake will be same as that of the 8.1 feet.
So the length of the diagonal will be:
[tex]2\times \text{Distance from 1 vertex to the stake}[/tex]
[tex]=2\times 8.1 feet=16.2 feet[/tex]
Hence, the length of the diagonal will be 16.2.
