To calculate the location of the centroid for a composite area.

The beam section shown in figure $($Figure $1)$ has dimensions $H_1$

$=20mm,H_2=8mm,W_1=11mm,W_2=23mm,$ and $R$

$=6mm.$ Determine the location of the centroid.

Use the table below to organize your calculations. For regions

that are holes, the area is negative.

Part A

Calculate the product of the area and tilde$(x)$ for region $1.$

Express your answer in $m{m}^3$ to three significant figures.
