Applying the area of trapezium, the approximate area filled by water in the picture would be close to: about 48 in.²
What is the Area of a Trapezium?
Area of trapezium = 1/2(a + b)h.
The following are dimensions of the area of the trapezium filled with water:
- Level of water (a) = median of the bigger trapezium = (3 + 8)/2 = 5.5 = 6 in.
- b = 8 in.
- Height ≈ 12/2 = 6 in.
Area = 1/2(6 + 8) × 6 = 42 in.²
Therefore, applying the area of trapezium, the approximate area filled by water in the picture would be close to: about 48 in.²
