Let’s go step by step to pick the right unit for each item.
We remember:
-
cm (centimeters) → for small things like pencils, scissors, shirts.
-
m (meters) → for medium things like people, trees, soccer fields, tracks.
-
km (kilometers) → for long distances like planes flying, cars driving far.
Now let’s match each one:
1.
Length of a calendar → A desk calendar is small, maybe 20–30 cm tall. →
cm
2.
Length of track → A running track is around 400 meters. →
m
3.
Distance travelled by a plane → Planes fly hundreds or thousands of kilometers. →
km
4.
Width of a shirt → Shirt width is about 50 cm across. →
cm
5.
Height of a man → Average man is about 1.7 meters tall. →
m
6.
Length of a pair of scissors → Scissors are usually 15–20 cm long. →
cm
7.
Distance travelled by a car → Cars drive many kilometers on trips. →
km
8.
Length of a soccer field → Soccer fields are about 100 meters long. →
m
9.
Height of a tree → Trees can be 5 to 20 meters tall. →
m
✔ All choices make sense based on real-life sizes and distances.
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
