Answer 2

Before, finding the answer. Let's find out how we can find the answer.

• In this question, we are asked to convert meters to centimeters.
• So, to convert from meters to centimeters, we must multiply the meters by 100.
• And to convert meters to centimeters where meters are also given, we must multiply 100 by meter and add the meters.

Given :

• 654 m
• 420 m 16 m  
• 42 m 48 cm  
• 84 m

To find :

• Convert m into cm

Solution :

Let's know that,

$\boxed{\tt 1 m = 100 cm}$

(a)  654______

1 m = 100 cm

654 m = 100 × 654

           = 65400 cm

Therefore, 654 m is 65400 cm.

(b)  420 m 16 cm______

1 m = 100 cm

420 m = 100 × 420

           = 42000

420 m 16 cm = 42000 + 16 cm

                     = 42016 cm

Therefore, 420 m 16 cm is 42016 cm.

(C)  42 m 48 cm_______

1 m = 100 cm

42 m = 100 × 42

         = 4200

42 m 48 cm = 4200 + 48 cm

                      = 4248 cm

Therefore, 42 m 48 cm is 4248 cm.

(d)  84 m_______​

1 m = 100 cm

84 m = 100 × 84

         = 8400 cm

Therefore, 84 m is 8400 cm.
