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.
