Here are two rectangles. The table below represents some values for $$ and $$ such that the areas of the rectangles sum to $$ cm
raketka [301]

The area of the first rectangle would be 18cm² and the area of the second rectangle would be 12cm².

<h3>How to calculate the area of a rectangle?</h3>

To calculate the area of a rectangle we must apply the following mathematical formula:

  • Side × base = area

According to the above, to calculate the area of the rectangles we must multiply the length of the side by the base as shown below. We must also take into account the table that will give us the value of X that we do not know:

  • 3cm × 6cm = 18cm²
  • 2cm × 6cm = 12cm²

Finally, to know how much the area of both rectangles adds up, we add both values:

12cm² + 18cm² = 30cm²

Note: This question is incomplete because the graph is missing. Here is the graph
