Answer:

53.14 units

Step-by-step explanation:

Length of arc is given as:

$l = \frac{ \theta}{360 \degree} \times c \\ \\ \therefore \: 12.4 = \frac{84 \degree}{360 \degree} \times c \\ \\ \therefore \: 12.4 = \frac{7}{30} \times c \\ \\ \therefore \: c = \frac{12.4 \times 30}{7} = \frac{372}{7} = 53.1428571 \\ \\ \therefore \: c =53.14 \: units$
