Expert Answer:

As m equals fraction numerator d i s tan c e space o f space i m a g e space f r o m space l e n s over denominator d i d tan c e space o f space o b j e c t space f r o m space l e n s end fraction
Putting the values m=10 over 30 = 1/3
Its value is less than 1 so image length would be smaller than as that of object
