Answer 2

Answer:

1. 1575cm=15m75
2. 1947500cm=19475m=19.475km
3. 13725cm = 137.25 m
4. 8.75km

Step-by-step explanation:

the formula of area =length ×breadth

1) length=45cm

breadth =35cm

=>(l×b)

=>45×35

=>1575cm = 15m75

2)length=20.5m

breadth=950

=>20.5 in cm = 2050

=>(l×b)

=>2050×950

=>1947500cm = 19475m=

19.475km

3) length=3m5cm

breadth=45

=> 3m5cm=305cm

=> (l×b)

=>305×45

=13725cm = 137.25 m

4) length=3.5km

breadth=2.5km

=>length 3500m

=> breadth 2500m

=> (l×b)

=>3500×2500

=>8750000

=>8.75km
