Simphiwe is a farmer, She has a square field with sides of 45 m . She plants eight maize plants in every \( \mathrm{m}^{2} \). How many malze plants does she plant?

To find out how many maize plants Simphiwe plants in her square field, we first need to calculate the area of the field. The area \( A \) of a square is given by the formula: \[ A = \text{side}^2 \] Given that the side of the field is 45 m, we can calculate the area as follows: \[ A = 45 \, \text{m} \times 45 \, \text{m} = 2025 \, \text{m}^2 \] Next, we know that Simphiwe plants 8 maize plants in every \( \mathrm{m}^2 \). To find the total number of maize plants, we multiply the area of the field by the number of plants per square meter: \[ \text{Total maize plants} = A \times \text{plants per } \mathrm{m}^2 = 2025 \, \mathrm{m}^2 \times 8 \, \text{plants/m}^2 \] Calculating this gives: \[ \text{Total maize plants} = 2025 \times 8 = 16200 \] Therefore, Simphiwe plants a total of **16,200 maize plants**.
