A farmer moves along the boundary of a square field of side `10 m` in `40 s`. What will be the magnitude of displacement of the farmer at the end of `2` minutes `20` seconds ?

Explanation

To solve the problem step by step, we will analyze the farmer's movement along the boundary of the square field and calculate the displacement at the end of the given time.

### Step 1: Understand the dimensions of the square field
The square field has each side measuring 10 meters. Therefore, the perimeter of the square field can be calculated as:
\[ \text{Perimeter} = 4 \times \text{side} = 4 \times 10 \, \text{m} = 40 \, \text{m} \]
