  2. A rectangular skatepark is drawn on a coordinate plane with vertices at (3, 1), (15, 1), (15, 9), and (3, 9). A triangular ramp section inside the park is marked with vertices at (3, 1), (15, 1), and (9, 5). Tane wants to find the area of the remaining flat skating area after removing the ramp section. What is that area?
  3. Maria is designing a community mural project that requires two different colored borders. The top border length is represented by (5x + 12) feet, while the bottom border is (3x - 8) feet.
