A park is made up of a large rectangle (10 m by 6 m) and a smaller rectangle (4 m by 3 m) removed from one corner.

  1. What is the total area of the remaining park?
  2. What is the perimeter of the park after the smaller rectangle is removed?
  • Total Area:

    • Area of large rectangle: 10 × 6 = 60 m²
    • Area of smaller removed rectangle: 4 × 3 = 12 m²
    • Remaining area: 60 - 12 = 48 m²
  • Perimeter Calculation:

    • Without the removed section, the original perimeter would be (10 + 6) × 2 = 32 m
    • However, removing the rectangle creates two extra edges: 3 m and 4 m
    • New perimeter: (10 + 6 + 10 + 6) + (3 + 4) = 35 m
