Answer:
The answer to the question is;
The enclosure length of the fence excluding the gates is 72 m.
Step-by-step explanation:
To solve the question, we note that the South Africa Predatory Association, SAPA recommended enclosure size should be 400 m² per animal
Therefore, if the enclosure is of equal sides, we have
Side of enclosure = [tex]\sqrt{400 m^2}[/tex] = 20 m
Since there are four sides in a square, we have the length of the fence around the enclosure given by,
Length of fence = Perimeter of square = 4 × sides = 4 × 20 m = 80 m
Remember that we are asked to exclude the gates, this gives;
Length of gates = 4 m × 2 gates = 8 m
Excluding the gates gives
Perimeter of fence - 8 m = 80 m - 8 m = 72 m
Therefore the length of the fence around the enclosure not including the gates is 72 m.
