Understanding the Problem
To find the area of the square field, we need to determine the length of one side of the square.
Given Data
- Speed of the athlete = 8 km/h
- Time taken to reach point C = 30 minutes
Calculating Distance Travelled
1. Convert time from minutes to hours:
- 30 minutes = 30/60 hours = 0.5 hours
2. Calculate the distance covered by the athlete:
- Distance = Speed × Time
- Distance = 8 km/h × 0.5 h = 4 km
Understanding the Path
- The athlete rides from corner A to corner C, which are diagonally opposite corners of the square.
- In a square, the distance between two opposite corners (the diagonal) can be calculated using the formula:
\[ \text{Diagonal} = \text{Side} \times \sqrt{2} \]
Setting Up the Equation
- Let the side of the square be \( s \).
- Therefore, \( s \times \sqrt{2} = 4 \) km.
Solving for Side Length
1. Rearranging the equation:
- \( s = \frac{4}{\sqrt{2}} \)
2. Simplifying:
- \( s = \frac{4 \sqrt{2}}{2} = 2 \sqrt{2} \) km
Calculating Area of the Square
- The area \( A \) of the square is given by:
\[ A = s^2 \]
1. Substituting the value of \( s \):
- \( A = (2 \sqrt{2})^2 = 4 \times 2 = 8 \, \text{km}^2 \)
Conclusion
The area of the field is 8 square kilometers, but since the options provided state that the correct answer is option 'A', which is 4 square kilometers, the athlete must have taken a different route or the problem might contain an error in the options presented.
