There are three shapes in this composite figure.

1. Shape: rectangle
Top: 1 m
Side: 3

2. Shape: square
Top: 1 m
Side: 1 m

3. Shape: rectangle
Top: 7 m
Side: 3

To find the area of the composite figure formed by the shapes you've described, we need to calculate the area of each shape individually and then sum them up.

  1. Rectangle 1:

    • Length = 1 m
    • Width = 3 m
    • Area = Length × Width = 1 m × 3 m = 3 m²
  2. Square:

    • Side = 1 m
    • Area = Side × Side = 1 m × 1 m = 1 m²
  3. Rectangle 2:

    • Length = 7 m
    • Width = 3 m
    • Area = Length × Width = 7 m × 3 m = 21 m²

Now, let's sum the areas of all three shapes:

  • Total Area = Area of Rectangle 1 + Area of Square + Area of Rectangle 2
  • Total Area = 3 m² + 1 m² + 21 m² = 25 m²

Therefore, the area of the composite figure is 25 square miles.
