The beam section below is solid and homogenous and has the following dimensions:

b1 = 42 mm (top flange width), b2 = 42 mm (bottom flange width) and b3 = 18 mm (web width).

d₁ = 90 mm (section depth), d₂ = 15 mm (top flange depth) and d₃ = 25 mm (bottom flange depth).

For the solid homogeneous beam section shown below, determine its centroid coordinate relative to the origin (0, 0) of the x-y axes. Give your answer for in millimetres (mm) to two decimal places
