Question

Simphiwe is a farmer. She has a square field with sides of 45 m. She plants eight maize plants in every m2. How many maize plants does she plant?

Answer 1

Hello!

Answer:

`\Large \boxed{\sf 16200}`

Explanation:

→ We want to calculate how many maize plants does she plant.

→ Let's calculate the area of the square field.

→ The area of the square is:

`\sf A = c^2`

Where:

- A is the area of the square

- c is the lenght of the side of the square

→ Let's apply this formula:

`\sf A = 45^2 = 2025`

→ We know that she plants eight maize plants in every m².

→ So we have this table:

`\begin{tabular}{ l c r } m^2 &1 & 2025 \\ number of plants & 8 & x \\ \end{tabular}`

Where x is the number of maize she uses in her field.

→ Let's apply the method of the cross to find x:

`\sf x= 8 * 2025 / 1 =\boxed{\sf 16200}`

Conclusion:

She will plant 16200 maize in her field.
