Given the information provided, here are the areas calculated:

  1. Base area of the rectangular prism:
    Area = Length x Width = 20 ft x 18 ft = 360 ft²

  2. Area of the first triangle:
    Area = 0.5 x base x height = 0.5 x 20 ft x 16.6 ft = 166 ft²

  3. Area of the second triangle:
    Area = 0.5 x base x height = 0.5 x 18 ft x 17.2 ft = 154.8 ft²

Summary of Areas:

  • Base Area of Rectangular Prism: 360 ft²
  • Area of First Triangle: 166 ft²
  • Area of Second Triangle: 154.8 ft²
