A stretched string is 1.93 m long and has a mass of 21.1 g. When the string is oscillated at 440 Hz, which is the frequency of the standard A pitch that orchestras tune to, transverse waves with a wavelength of 16.9 cm

travel along the string. Calculate the tension in the string.

I have been using the formula v = sqrt (T/(m/L)
which would give T = (440x0.169)^2 (0.211/1.93)
why isn't this the correct way to solve?
