Here are the answers to the questions: 1. The basic unit of length in the metric system is the meter. 2. To find the length of the line: The ruler shows markings in centimeters (cm), with each centimeter divided into 10 millimeters (mm). The line extends past the 3 cm mark by 3 small divisions. (i) Centimetres? Step 1: Read the length from the ruler. The line ends at 3 cm and 3 mm. Step 2: Convert millimeters to centimeters. 1 cm = 10 mm 3 mm = (3)/(10) cm = 0.3 cm Step 3: Add the centimeter values. 3 cm + 0.3 cm = 3.3 cm The length is 3.3 cm. (ii) Millimetres? Step 1: Convert the length in centimeters to millimeters. 1 cm = 10 mm 3.3 cm = 3.3 × 10 mm = 33 mm The length is 33 mm. (iii) Metres? Step 1: Convert the length in centimeters to meters. 1 m = 100 cm 3.3 cm = (3.3)/(100) m = 0.033 m The length is 0.033 m. 3. Name the instruments that are used to measure the following. (i) Length of a soccer field A measuring tape (specifically a long one, or a surveyor's tape/wheel). (ii) Things that are not straight A flexible measuring tape or a string/thread (which can then be measured with a ruler).
