Let’s measure each object using the ruler shown. The rulers start at 0, so we just look at where the end of each object lines up.
1.
Pencil:
The pencil starts at 0 and ends right at the 7 mark.
→ So, it is
7 units long.
2.
Matchstick:
The matchstick starts at 0 and ends at the 5 mark.
→ So, it is
5 units long.
3.
Truck:
The truck starts at 0 and ends at the 8 mark.
→ So, it is
8 units long.
4.
Spoon:
The spoon starts at 0 and ends at the 9 mark.
→ So, it is
9 units long.
5.
Knife:
The knife starts at 0 and ends at the 9 mark.
→ So, it is
9 units long.
Wait — let me double-check the knife. Looking again: the handle starts at about 3? No — actually, in the image, all objects are aligned to start at 0 on the ruler. Let me recheck carefully:
Actually, looking closely at the knife — its left edge (handle) starts at 3, not 0! Oh no — I made a mistake.
Let me go back and check each one properly, making sure we’re measuring from the actual starting point of the object to its ending point.

Re-measuring carefully:
1.
Pencil:
Left tip at 0, right eraser end at 7 →
7 units
2.
Matchstick:
Left end at 0, red tip at 5 →
5 units
3.
Truck:
Front bumper at 0, back of trailer at 8 →
8 units
4.
Spoon:
Handle end at 0, bowl end at 9 →
9 units
5.
Knife:
Handle starts at 3, blade ends at 9 → So length = 9 - 3 =
6 units
Ah! That was my error. The knife does NOT start at 0 — it starts at 3. So we subtract: 9 minus 3 equals 6.
Let me verify once more:
- Pencil: 0 to 7 → 7
✔
- Matchstick: 0 to 5 → 5
✔
- Truck: 0 to 8 → 8
✔
- Spoon: 0 to 9 → 9
✔
- Knife: 3 to 9 → 9 - 3 = 6
✔
All correct now.
Final Answer:
7
5
8
9
6
