The perimeter of a parallelogram is 40 cm, and the heights on both sides are 6 cm and 10 cm respectively. What is the area of the parallelogram Do arithmetic

The perimeter of a parallelogram is 40 cm, and the heights on both sides are 6 cm and 10 cm respectively. What is the area of the parallelogram Do arithmetic

The sum of the two adjacent sides is 20cm, and the height is 6:10. Because the area is the same, the length of the bottom side corresponding to the height should also be 10:6, and the length of both sides should be 12.5cm and 7.5cm, respectively. Area = 12.5 * 6 = 75cm2, or = 10 * 7.5 = 75cm2

The perimeter of a parallelogram is 70 cm, and its two heights are 12 cm and 16 cm respectively. What is its area?
There are formulas,

Let one edge be x, and the other edge be 70 / 2-x
16 * x = 12 * (35-x), we can get x = 15, the area is 240 square centimeter
