The correct option is A 3.69 m
To calculate the total length of the bus, add the given lengths.
So first of all, convert into same units.
1 mm = 110 cm
440 mm = 44010 = 44 cm
Now, 325 cm + 44 cm = 369 cm
Now, 1 cm = 1100 m
Now, 369 cm = 369100 m
= 3.69 m
Hence, the total length of the bus is 3.69 m.
