The sides of the parallelogram are 7 and 9 cm. Can its area S = 64 cm²?

The area of the parallelogram is S = a * b * sina (a and b are the sides of the parallelogram, a is the angle between them). The maximum value that a sine can take is 1.

Therefore, the maximum parallelogram area is S = 7 * 9 * 1 = 63 (cm²).

Answer: it cannot.
