17ft x 9and half ft

20ft x 3 ft.. Both areas are 4 inces deep

I make it around 2.1 metres

Brake it down to metres
Width * length * depth

Your area is 17x9.5 + 20x3 = 221.5
1/3 of a foot deep so73.8cu ft
73.8ft³= 2.089783m³

Yep you have loads.
Pouring onto dug ground tends to take more than measured as it will be uneven and some water will be lost into the ground too. Still is only measuring alittle over 2 cubic metres so you have ordered the right amount imo.

don't mind having extra but if it short I would be in a right bit of trouble

Thank you
