The heights of two different bases of a parallelogram are 9 cm and 6 cm respectively, and the longer base is 12 cm. What is the perimeter of the parallelogram?
By using the equal area method, the shorter side length is obtained
12 × 6 △ 9 = 8 (CM)
The circumference is 2 × (12 + 8) = 40 (CM)
The base of a parallelogram is 12.5 cm, one is 6 cm high, and the other is 10 cm high?
12.5 × 6 △ 10 = 7.5 (CM)
(12.5 + 7.5) × 2 = 40 (CM)
The circumference is 40 cm
The heights of the two different bases of a parallelogram are 9 cm and 6 cm respectively, and the longer base is 12 cm. What is the perimeter of the parallelogram?
