Question

what is the length indicated by the arrow on the metric ruler in centimeters (cm)? 45.6 cm 45.4 cm 46.4 cm 46.6 cm

Explanation:

Step1: Observe the ruler markings

The ruler is marked in centimeters. Each small - division represents 0.1 cm.

Step2: Locate the arrow position

The arrow is 6 small - divisions past the 45 - cm mark.

Step3: Calculate the length

Since each small - division is 0.1 cm, 6 small - divisions is \(6\times0.1 = 0.6\) cm. So the length is \(45 + 0.6=45.6\) cm.

Answer:

45.6 cm
