Options

A. 28
B. 38
C. 48
D. 18

Answer

To solve the problem of finding the number of plants in each row when 784 plants are arranged such that the number of plants in each row is the same as the number of rows, we can follow these steps:

### Step 1: Define the variables
Let \( n \) be the number of plants in each row, which is also equal to the number of rows. Therefore, we can say that the total number of plants can be expressed as:
\[ \text{Total plants} = n \times n = n^2 \]

### Step 2: Set up the equation
According to the problem, the total number of plants is 784. Thus, we can set up the equation:
\[ n^2 = 784 \]

### Step 3: Solve for \( n \)
To find \( n \), we take the square root of both sides of the equation:
\[ n = \sqrt{784} \]

### Step 4: Calculate the square root
Calculating the square root of 784:
\[ n = 28 \]

### Conclusion
Therefore, the number of plants in each row is:
\[ \text{Number of plants in each row} = 28 \]
