Answer 3

Calculating the Distance Between Points

To calculate the distance between the points, we can use the given information. The points are marked every 3 cm, and we need to find the distance between the outermost points.

The distance between the points can be calculated by multiplying the number of intervals by the distance between each interval. In this case, the distance between each interval is 3 cm.

Calculation: - Number of intervals: 7 - Distance between each interval: 3 cm

Distance = Number of intervals × Distance between each interval

Distance = 7 × 3 cm = 21 cm

Therefore, the distance between the outermost points is 21 cm. This is calculated by multiplying the number of intervals by the distance between each interval
