Answer
To find the area of the garden expansion, we can apply the formula for the area of a triangle:
Area=21×base×height
Assume the base is 17,024 m and the height is 19.5 m:
( Area = \frac{1}{2} \times 17,024 \times 19.5 = 165,984 m² )

Answer
To determine which option is more economical, we calculate the costs:
Option A:
Cost = R154 for 10 m roll. Therefore, for the full length:
( Cost = \frac{18852}{10} \times 154 = R 308 Option B:
Cost = R127,30 per running meter. For the full length:
( Cost = 18852 \times 127.30 = R 418,710 \
Thus, Option A is the more economical choice at R308.
