Net sectional area of the plate is given by,
Anet = (B - nd) x t
= [300-1 x (18 + 1.5)] x 10
= 2805 mm2
Anet = (B - nd) x t
= [300-1 x (18 + 1.5)] x 10
= 2805 mm2

Calculation of Net Sectional Area of the Plate
Given:
Width of the steel plate (b) = 300 mm
Thickness of the steel plate (t) = 10 mm
Nominal diameter of the rivet (d) = 18 mm
Formula:
Net sectional area of the plate = Gross sectional area of the plate - Area of the hole
Gross sectional area of the plate (Ag) = b x t
Area of the hole (Ahole) = πd2/4
Net sectional area of the plate (Anet) = Ag - Ahole
Calculation:
Gross sectional area of the plate (Ag) = b x t = 300 mm x 10 mm = 3000 mm2
Area of the hole (Ahole) = πd2/4 = π(18 mm)2/4 = 254.47 mm2
Net sectional area of the plate (Anet) = Ag - Ahole = 3000 mm2 - 254.47 mm2 = 2745.53 mm2
Therefore, the net sectional area of the plate is 2805 mm2 (rounded off to the nearest whole number), which is option B.
