Total length of fencing required is 74 feet.
Since we are only given a base and height, this indicates the kennel base could be either a triangle or rectangle. However, a rectangular shape is most often used for kennels.
The base = 24 feet
The height = 13 feet
To get the total length of fencing required to enclose the base, this means we are looking for the outside perimeter.
For a rectangle, perimeter can be solved for by:
2(b) + 2(h) = P
Substitute our values in.
2(24) + 2(13) = P
Solve.
48 + 26 = P
P = 74 feet
