Final answer:
The area of a rectangle is found by multiplying its length by its width, which can be done using a function called calcarea that takes two parameters for these dimensions.
Step-by-step explanation:
To find the area of a rectangle, we multiply the rectangle's length by its width. If the function calcarea is to calculate the area of a rectangle, it would need two parameters: one for the length and one for the width. The area can be calculated by multiplying these two values.
Here's an example of how the area is calculated:
AREA = length × width
If the length is 15 units and the width is 4 units, the area of the rectangle would be 15 × 4, which equals 60 square units.
