The figure shows two notes joined by a tie: a crotchet (quarter note) on the left and a dotted quaver (dotted eighth note) on the right. A tie combines the durations of both notes into a single sustained sound.
Converting each note to demisemiquavers (the smallest standard subdivision, equal to a thirty-second note):
A crotchet = 8 demisemiquavers
A quaver = 4 demisemiquavers
The dot adds half the quaver's value = 2 demisemiquavers
A dotted quaver = 4 + 2 = 6 demisemiquavers
The total duration of the tied figure is therefore 8 + 6 = 14 demisemiquavers.
