![7. A lamina \( R \cup T \) consists of a rectangle \( R \) of density \( \rho \) and a triangle of density \( 2\rho \) as shown.
[Diagram Description]
- The diagram displays a coordinate plane with a rectangular section labeled \( R \) extending from \( x = -5 \) to \( x = 0 \) and \( y = 0 \) to \( y = 2 \). This rectangle is denoted with density \( \rho \).
- Adjacent to it, a triangular section labeled \( T \) extends from \( x = 0 \) to \( x = 5 \) with its base along the \( y = 0 \) line. The triangle reaches up to \( y = 5 \) at its peak (rightmost point) and has density \( 2\rho \).
a. Find the mass of \( R \) and the center of mass of \( R \).
b. Find the mass of \( T \) and the center of mass of \( T \).
c. Using additivity of moments, find the center of mass of \( R \cup T \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F97c29525-cf69-4fb4-8c20-75b7e5721aa2%2Fb9c9365f-d0bf-458d-8289-60d084064319%2Ft51uwys_processed.png&w=3840&q=75)
