To calculate the area of a parallelogram, we need the base and the height. The formula for the area \( A \) of a parallelogram is:
\[ A = \text{base} \times \text{height} \]
From the dimensions you've provided (40m, 15m, 10m, 30m, 25m), I'm assuming one of them is the base and another is the height.
Could you please specify which dimension should be considered as the base and which one as the height? If you meant that the base is 30m and the height is 10m, for example, the calculation would be:
\[ A = 30 , m \times 10 , m = 300 , m^2 \]
If you provide the specific base and height, I can give you the exact area.
