To determine how many cassava plants can be planted around the rectangular garden, we first need to find the dimensions of the area available for planting around the garden.
-
Calculate the perimeter of the garden:
- The garden measures \( 18 , \text{m} \) by \( 12 , \text{m} \).
- The perimeter \( P \) is calculated as follows: \[ P = 2 \cdot (length + width) = 2 \cdot (18 , \text{m} + 12 , \text{m}) = 2 \cdot 30 , \text{m} = 60 , \text{m} \]
-
Determine the spacing for the cassava plants:
- The spacing between each cassava plant is \( 3 , \text{m} \).
-
Calculate the number of cassava plants:
- To find the number of cassava plants that can be planted along the perimeter, we will divide the perimeter by the spacing: \[ \text{Number of cassava plants} = \frac{\text{Perimeter}}{\text{Spacing}} = \frac{60 , \text{m}}{3 , \text{m}} = 20 \]
Therefore, the total number of cassava plants that can be planted around the garden is 20 cassava plants.
