平行四边形面积计算器 — 公式
## Parallelogram Area
### Formula
**Area = base × height**
**Perimeter = 2 × (base + side)**
The height is the perpendicular distance between the two parallel bases, not the slant side length.

计算示例
Parallelogram with base 8, height 5, and side 6.
- Area = 8 × 5 = 40
- Perimeter = 2 × (8 + 6) = 28
