To create a tape diagram, we start by dividing the total amount of money Sylvia received into 3 equal parts because her allowance is in the ratio 2:3.
Each part represents $21/3 = $7.
Since Olivia's allowance is in a 2:3 ratio, Olivia will receive 2 parts of $7 each.
Therefore, Olivia received $7 x 2 = $<<7*2=14>>14. Answer: \boxed{14}.
