If a football field is 120 yards long, what is the length in meters?

Step 1 ：Step 1: Write down the conversion factor between yards and meters, which is 1 yard = 0.9144 meters.

Step 2 ：\(1 \text{ yard} = 0.9144 \text{ meters}\)

Step 3 ：Step 2: Multiply the length of the football field in yards by the conversion factor to get the length in meters.

Step 4 ：\(120 \text{ yards} \times 0.9144 \frac{\text{meters}}{\text{yard}} = 109.728 \text{ meters}\)
