since we know those two triangles are similar then we can use proportions.
33 and one third as a fraction would be either 33 1/3 or 100/3
sqrt (3) * sqrt(16) = 4sqrt(3) = irrational
2sqrt(9) *sqrt(4) = 6*2 = 12 rational
7 sqrt(3)* sqrt(3) = 7*3 =21 rational
sqrt(5) * sqrt(5) = 5 rational
C has a negative answer. hope this helps
