(l) 60 m 42 cm

​

Answer 1

Step-by-step explanation:

1 m = 100 cm

1. 4 m = 4 * 100 = 400 cm
2. 7m = 7 * 100 = 700 cm ; 7 m 1 cm = 700 + 1 = 701 cm
3. 3 m = 3 * 100 = 300 cm ; 3 m 36 cm = 300 + 36 = 336 cm
4. 6 m = 6 * 100 = 600 cm ; 6 m 91 cm = 600 + 91 = 691 cm
5. 4 m = 4 * 100 = 400 cm ; 4 m 50 cm = 400 + 50 = 450 cm
6. 5 m = 5 * 100 = 500 cm ; 5 m 42 cm = 500 + 42 = 542 cm
7. 9 m = 9 * 100 = 900 cm ; 9 m 42 cm = 900 +42 = 942 cm
8. 3 m = 3 * 100 = 300 cm ; 3 m 97 cm = 300 +97 = 397 cm
9. 4 m = 4 * 100 = 400 cm ; 4 m 48 cm = 400 + 48 = 448 cm
10. 8 m = 8 * 100 = 800 cm ; 8 m 5 cm = 800 + 5 = 805 cm
11. 60 m = 60 * 100 = 6000 m ; 60 m 42 cm = 6000 + 42 = 6042 cm
