Area = length x length
Therefore the ratio of areas of two similar objects is the square of the ratio of lengths.
Lengths - 1 : 41
Areas - 12 : 412 = 1 : 1681
If the ratio of the lengths of corresponding parts in two similar solids is 51, then the ratio of their surface areas is the square of the ratio of their lengths. Therefore, the ratio of their surface areas is ( 51^2 = 2601 ).
