Explanation:

Step1: Identify the shape of the black stripe

The black diagonal stripe is a parallelogram. The formula for the area of a parallelogram is $A = base \times height$.

Step2: Determine the base and height

The base of the parallelogram (black stripe) is given as 10 cm, and the height is the height of the rectangle (the flag), which is 30 cm.

Step3: Calculate the area

Using the formula $A = base \times height$, substitute the values: $A = 10 \times 30 = 300$ square centimeters.

Answer:

300 square centimeters
