Sure, here are the formulas for calculating the perimeter and area of these shapes:

1. Rectangle:
- Perimeter = 2(length + width)
- Area = length * width

2. Triangle:
- Perimeter = side1 + side2 + side3
- Area = 0.5 * base * height

3. Parallelogram:
- Perimeter = 2(base + side)
- Area = base * height

4. Trapezium (or Trapezoid):
- Perimeter = side1 + side2 + base1 + base2
- Area = 0.5 * (base1 + base2) * height

Remember, all measurements should be in the same unit (like cm, m, etc.) before you start your calculations.
