Find Centroid of the area shown Stepl. Create a table for $4$ areas shown

Step $2.$ In the column "Area" determine positive or negative areas for each component and add$/$subtract all areas at the bottom

Step $3.$ In the column of $"$xi centroid" of each component determine proper value within global $\backslash ($ x $\backslash )$ coordinate

Step $4.$ In the column of $"$yi centroid" of each component determine proper value within global $\backslash ($ y $\backslash )$ coordinate

Step $5.$ In the column of product of component area times $\backslash ($ x $\backslash )$ coordinate $"$Ai xi$"$ find product for each component and add all products at the bottom

Step $6.$ In the column of product of component area times $\backslash ($ y $\backslash )$ coordinate $"$Ai yi$"$ find product for each component and add all products at the bottom

Step $7.$ Find coordinates of the centroid
