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

$b_1=42mm($top flange width$),b_2=42mm($bottom flange width$)$ and $b_3=18mm($web width$).$

$d_1=90mm($section depth$),d_2=15mm($top flange depth$)$ and $d_3=25mm($bottom flange depth$).$

For the solid homogeneous beam section shown below, determine its centroid coordinate $\stackrel{}{x}$ relative to the

origin $(0,0)$ of the $x-y$ axes. Give your answer for in millimetres $(mm)$ to two decimal places.
