Step-by-step explanation:
let k be the scale ratio of two bodies then according to the question
k = a/b -- (1)
let Sa be the surface area of body A and Sb be the surface area of body B , then
according to the relation of scale factor and surface areas

from the above equation ,

as k = a/b from (1)
therefore
hence the ratio of their surface area is
