Let’s go through each item one by one and think about what unit makes the most sense.
We know:
-
Centimeters (cm) are for small things — like pencils, scissors, or shirts.
-
Meters (m) are for medium-sized things — like people, trees, soccer fields, or tracks.
-
Kilometers (km) are for very long distances — like how far a car or plane travels.
Now let’s match each object:
1.
Length of a calendar → A desk calendar is not too big, maybe around 30 cm tall. So →
cm
2.
Length of track → A running track is usually 400 meters around. So →
m
3.
Distance travelled by a plane → Planes fly hundreds or thousands of kilometers. So →
km
4.
Width of a shirt → Shirts are measured in centimeters across the chest. So →
cm
5.
Height of a man → Adults are about 1.7 to 2 meters tall. So →
m
6.
Length of a pair of scissors → Scissors are handheld, maybe 15–20 cm long. So →
cm
7.
Distance travelled by a car → Cars drive many kilometers on trips. So →
km
8.
Length of a soccer field → Soccer fields are about 100 meters long. So →
m
9.
Height of a tree → Trees can be 5 to 20 meters tall. So →
m
All choices make sense based on real-life sizes.
Final Answer:
Length of a calendar → cm
Length of track → m
Distance travelled by a plane → km
Width of a shirt → cm
Height of a man → m
Length of a pair of scissors → cm
Distance travelled by a car → km
Length of a soccer field → m
Height of a tree → m
