Had EC2 Table 4.14 been used instead of NAD Table 7, the basic ratio before modification would have been 35, which would not have been OK.

NAD Table 7

2.3.8 Cracking

For minimum area of reinforcement assume f ct.eff

87500 mm2

Hence A

Area of reinforcement provided = 377 mm2/m

No further check is necessary as h = 175 < 200 mm Maximum bar spacing = 3h < 500 mm
