$A=5$ ..........Answer

(II)

we know that

wave length is the length of one wave

we can see that from B to F , there is one wave

and we are given it's length as 20cm

so, wavelength is 20cm......Answer

(III)

we know that

$velocity=wavelength*frquency$

we are given

frequency =100hz

wavelength =20cm

now, we can find velocity

$velocity=20*100cm/sec$

$velocity=2000cm/sec$ ............Answer
