Practice Questions with Solutions: Measurement

Question 1: Draw a line 5 cm long.

Step 1: Put a mark '.'.
Step 2: Keep the scale so that its 0 aligns with the mark '.'.
Step 3: Keep the pointed end of a pencil at 0. Draw along the scale till you reach 5.

Question 2: Convert the following lengths into centimetres:
(a) 18 m
(b) 26 m
(c) 8 m 52 cm
(d) 15 m 72 cm

We know that 1 m = 100 cm. So,
(a) 18 m = 18 x 100 cm = 1800 cm.
(b) 26 m = 26 x 100 cm = 2600 cm.
(c) 8 m 52 cm = 8 x 100 cm + 52 cm
= 800 cm + 52 cm = 852 cm.
(d) 15 m 72 cm = 15 x 100 cm + 72 cm
= 1500 cm + 72 cm = 1572 cm.

Question 3: Express the following lengths as metres and centimetres:
(a) 526 cm
(b) 705 cm
(c) 1542 cm

We know that, 100 cm = 1 m. So,
(a) 526 cm = 500 cm + 26 cm
= 5 m + 26 cm = 5 m 26 cm.
(b) 705 cm = 700 cm + 5 cm
= 7 m + 5 cm = 7 m 5 cm.
(c) 1542 cm = 1500 cm + 42 cm
= 15 m + 42 cm = 15 m 42 cm.

Question 4: Add 19 m and 50 m.

Question 5: Add 67 m and 94 m.

Question 6: Add 67 cm and 98 cm.

Question 7: Add 24 m 50 cm and 37 m 30 cm.

Question 8: Subtract 32 m from 78 m. 

Question 9: Subtract 37 cm from 90 cm.

Question 10: Subtract 45 m 60 cm from 98 m 75 cm

Question 11: Subtract 37 m 66 cm from 89 m 98 cm

Question 12: Amit had 5 m long rope. He tied 1 m 75 cm long rope to it. Find the total length of the rope.

The length of rope that Amit had initially = 5 m
The length of rope tied to it = 1 m 75 cm
Total length of rope = 5 m + 1 m 75 cm

Hence, the total length of the rope = 6 m 75 cm.

Question 13: A piece of cloth measures 57 m 65 cm. A piece measuring 38 m 42 cm is cut from it. What length of the cloth is left?

The length of the piece of cloth = 57 m 65 cm
The length of the cloth cut = 38 m 42 cm
The length of the cloth left = 57 m 65 cm - 38 m 42 cm

Hence, the length of cloth left = 19 m 23 cm.
