Jawaban:

The farmer can plant 3 chilli plants per 0.5 m². To find out how many plants he can plant in 85 m², you can divide the total area by the area per plant.

85 m² / 0.5 m²/plant = 170 plants.

Penjelasan dengan langkah-langkah:

The area per plant is given as 0.5 m², which means that one chilli plant takes up 0.5 square meters of space. To find out how many plants can be planted in a given area, we need to divide that area by the area per plant. In this case, the given area is 85 m². So, we can calculate the number of chilli plants that can be planted in 85 m² by dividing 85 by 0.5.

85 m² / 0.5 m²/plant = 170 plants.

This means that in an area of 85 m², the farmer can plant 170 chilli plants.
