Considering the dimensions of rectangle have got integer values we can get a solution.

If #x# cm represents the common multiple of dimension of the rectangle then

a) Area of the 1st rectangle

#=6x*5x=20*6#

#=>x=2#

This gives dimension as #12cmxx10cm#

b) Area of the 2nd rectangle

#=4x*3x=20*6#

#=>x=sqrt10#

This gives dimension as #4sqrt10cmxx3sqrt10cm->color(red)"not possible"#

c) Area of the 3rd rectangle

#=15x*2x=20*6#

#=>x=2#

This gives dimension as #30cmxx4cm#

d) Area of the 4th rectangle

#=30x*x=20*6#

#=>x=2#

This gives dimension as #60cmxx2cm#
