Answer
Using the formula for the area of a triangle:
Area=21×base×height
If the base is 17.024 m and the height is 19.5 m, then:
Area=21×17.024×19.5=165.984m2.

Answer
To determine the cost for both options:
Option A cost:
R154 for 10m roll:
Cost for 1 meter = R154/10 = R15.40
Total for circumferential fence = 18,852m * R15.40 = R289,155.60
Option B cost:
R127.30 per running meter:
Total for circumferential fence = 18,852m * R127.30 = R2,401,124.60
