I'm not sure how to explain rounding, but this should be the answer if ur asking for rounding to the nearest hundred thousand and not the hundredth thousand
To get the percentage of area we shall proceed as follows: linear scale factor =length of herb/ length of garden =4/10 but area scale factor=(linear scale factor)^2 area scale factor=(2/5)^2=4/25 thus the percentage area proportion will be: 4/25*100 =16%
