Answer 1

Step-by-step explanation:

Given that:-

1)

Given measurement =130 cm

we know that 1 m=100cm

=>1cm =1/100 m

=>1 cm =0.01 m

now 130 cm=130×0.01 m

=>1.30 m

=>1.3 m

130 cm = 1.3 m

_______________________________

2)

Given measurement=10 dm

We know that 1 dm =10 cm

=>10 dm =10×10 cm =100 cm

10 dm = 100 cm

_______________________________

3)

Given measurement=10 m

We know that 1 m =100 cm

=>10 m = 10×100 cm=1000cm

10 m= 1000 cm

________________________________

4)

Given measurement=1 km

we know that 1 km =1000 m

1 km = 1000 m

________________________________

5)

Given measurement=20 cm

we know that 1 dm =10 cm

=>1 cm = 1/10 dm

=>20 cm =20/10 dm =2 dm

20 cm = 2 dm

Answer 2

$\huge \underline \frak{ \red{ \star \: answer : }}$

Given:-

1) Measurement → 130 cm

$\large\frak{ \rightarrow \: we \: know \: that : }$

$\frak{ \pink{1 \: m = 100 \: cm}}$

→ 1 cm = 1/100 m

→1 cm = 0.01 m

•Now, 130 cm → 130×0.01 m

→1.30 m = 1.3 metres.

$\frak{ \red{ \therefore130 \: cm = 1.3 \: m}}$

2) Measurement→10 dm

$\large \frak{ \rightarrow \: we \: know \: that : }$

$\frak{ \pink{1 \: dm \: = 10 \: cm}}$

→ 10 dm = 10 × 10 cm = 100 cm

$\frak{ \red {\therefore \: 10 \: dm = 100 \: cm}}$

3) Measurement→ 10 m

$\large \frak{ \rightarrow \: we \: know \: that : }$

$\frak{ \pink{1 \: m = 100 \: cm}}$

→ 10 m = 10 × 100 cm = 1000 cm.

$\frak{ \red{\therefore \: 10 \: m \: = 1000 \: cm}}$

4) Measurement→ 1 km

$\large \frak{ \rightarrow \: we \: know \: that : }$

$\frak {\pink{1 \: km = 1000 \: m}}$

$\frak{ \red{\therefore \: 1 \: km = 1000 \: m}}$

5) Measurement→ 20 cm

$\large \frak{ \rightarrow \: we \: know \: that : }$

$\frak{\pink{1 \: dm \: = 10 \: cm}}$

→ 1 cm = 1/10 dm

→ 20 cm = 20/10 dm = 2 dm.

$\frak{ \red{ \therefore20 \: cm = 2 \: dm}}$
