Addition of lengths worksheet for Grade 5 students, focusing on adding measurements in meters and centimeters.

Let's solve the addition of lengths problems step by step. The goal is to add measurements in metres (m) and centimetres (cm), keeping in mind that:

> 100 cm = 1 m

So if the sum of centimetres exceeds 100, we convert the excess into metres.

Problem 1:

```
m cm
12 40
+ 18 10
--------
```

- Add centimetres: 40 + 10 = 50 cm (less than 100, so no conversion)
- Add metres: 12 + 18 = 30 m

✔ Answer: 30 m 50 cm

Problem 2:

```
m cm
15 42
+ 56 16
--------
```

- Add centimetres: 42 + 16 = 58 cm (less than 100)
- Add metres: 15 + 56 = 71 m

✔ Answer: 71 m 58 cm

Problem 3:

```
m cm
13 50
+ 45 60
--------
```

- Add centimetres: 50 + 60 = 110 cm
- 110 cm = 1 m 10 cm → carry over 1 m to metres
- Add metres: 13 + 45 = 58 m, plus carry-over 1 m → 59 m
- Remaining cm: 10 cm

✔ Answer: 59 m 10 cm

Problem 4:

```
m cm
16 85
+ 58 34
--------
```

- Add centimetres: 85 + 34 = 119 cm
- 119 cm = 1 m 19 cm → carry over 1 m
- Add metres: 16 + 58 = 74 m, plus carry-over 1 m → 75 m
- Remaining cm: 19 cm

✔ Answer: 75 m 19 cm

Problem 5:

```
m cm
37 63
+ 24 55
--------
```

- Add centimetres: 63 + 55 = 118 cm
- 118 cm = 1 m 18 cm → carry over 1 m
- Add metres: 37 + 24 = 61 m, plus carry-over 1 m → 62 m
- Remaining cm: 18 cm

✔ Answer: 62 m 18 cm

---

Problem 6:

```
m cm
11 97
+ 45 17
--------
```

- Add centimetres: 97 + 17 = 114 cm
- 114 cm = 1 m 14 cm → carry over 1 m
- Add metres: 11 + 45 = 56 m, plus carry-over 1 m → 57 m
- Remaining cm: 14 cm

✔ Answer: 57 m 14 cm

---

✔ Final Answers:

1. 30 m 50 cm
2. 71 m 58 cm
3. 59 m 10 cm
4. 75 m 19 cm
5. 62 m 18 cm
6. 57 m 14 cm

🔍 Key Tip:

Always remember to:
- Add centimetres first.
- If the total cm ≥ 100, convert extra cm to metres (divide by 100).
- Add the metres, including any carry-over.
