WAEC Agriculture 2021 Paper

Question : 23

Total: 49

Solution:

Concept:

Plant population is calculated by dividing the total cultivated area by the area occupied by one plant.

Explanation:

Convert the farmland area into square metres:

0.72

hectares

= 0.72 \times 10{,}000 = 7200 \text{ m}^2

Convert the spacing into metres:

60 \text{ cm} = 0.6 \text{ m}

Since spacing is square, the area occupied by one okro plant is:

0.6 \times 0.6 = 0.36 \text{ m}^2

Thus, expected plant population is:

\frac{7200}{0.36} = 20{,}000 \text{ plants}

Answer:

D. 20,000 plants
