WAEC Agriculture 2015 Paper

Question : 23

Total: 57

Solution:

Concept:

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

Explanation:

Area of the farmland is

1

hectare, which equals

10{,}000 \text{ m}^2

Each maize stand occupies an area of

0.9 \text{ m} \times 0.3 \text{ m} = 0.27 \text{ m}^2

Since one seed is sown per stand, the population is given by

\frac{10{,}000}{0.27}

This gives

37{,}037.03

, which is approximately

37{,}037

plants.

Answer:

37{,}037

plants (Option C).
