Answer 1

Answer:

area of rectangle =length xbreadth

area of the following are:

(i )5cm*3 cm=15 cm^ 2

(ii) 12 cm * 21 cm = 252 cm ^ 2

(iii) 2 km-(2*1000*100)cm=2000000c

4km-(4*1000*100)cm=400000c

=>(20000*400000)cm^ 2

=> 80000000000 0 cm ^ 2

(iv) 2m - (2 * 100) cm

=>200cm

=>(200*70)cm^ 2

=>14000cm^ 2

Arrange :

(i)<(ii)<(iv)<(iii)
