Problem

An L-shaped uniform thin plate is formed from two rectangular pieces of equal thickness: • Rectangle A extends from

x=0

x=20\,\text{cm}

and from

y=0

y=60\,\text{cm}

. • Rectangle B extends from

x=20\,\text{cm}

x=60\,\text{cm}

and from

y=40\,\text{cm}

y=60\,\text{cm}

. Taking the common corner at

x=0

y=0

as the origin, compute the

(x,y)

coordinates (in centimeters) of the center of mass of the composite plate.
