Since the two polygons are similar, ratio of their corresponding sides must be equal ~

`\qquad \rm\dashrightarrow \: (m)/(28) = (30)/(40)`

`\qquad \rm\dashrightarrow \: (m)/(28) = (3)/(4)`

`\qquad \rm\dashrightarrow \: {m} = (3)/(4) * 28`

`\qquad \rm\dashrightarrow \: {m} = {3}{} * 7`

`\qquad \rm\dashrightarrow \: {m} = 21 \: \: units`
