height of parallelogram=3x
base of parallelogram=4x
Area of parallelogram=1452m^2=b×h
3x×4x=1452
12x^2=1452
x^2=1452/12=121
x^2=(11)^2
x=11m
height of parallelogram=3x=3×11=33m
base of parallelogram =4x=4×11=44m
radius of smallest circle=3
radius of biggest circle=4
ratio of circumference =(circumference of smallest circle)/(circumference of biggest circle)
=(2×pia×r)/(2×pia×R)
=r/R=r:R=3:4
than equally
