Answer :

Sure, let's go through the solution step-by-step:

6. The number of students in each row is given as 2025.

This is a straightforward statement and doesn't require any further calculation. We simply take this as a given fact.

7. To find the total length of dimensions given as [tex]$75 \, \text{m} \times 4 \, \text{m}$[/tex], we need to multiply these two dimensions. The dimensions represent a rectangular area where one side is 75 meters and the other side is 4 meters.

Step-by-Step Solution:

a) Identify the dimensions of the given length:
- One side of the rectangle: 75 meters
- The other side of the rectangle: 4 meters

b) To find the total length (perimeter for a path covering the entire boundary would be different, but here we are considering it as combined product for area or as per as per specific requirement of the task) we multiply these two dimensions.

c) Perform the multiplication:
[tex]\[ 75 \times 4 = 300 \, \text{meters} \][/tex]

Thus, the total length for the given dimensions of [tex]$75 \, \text{m} \times 4 \, \text{m}$[/tex] is 300 meters.

So we have:
- 2025 students in each row.
- The total length of the given dimensions is 300 meters.
