Rectangle AreaComplete the Program . The program calls the following functions, which have not been written:

getLength This function should ask the user to enter the rectangles length and then return that value as a double .

getWidth This function should ask the user to enter the rectangles width and then return that value as a double .

getArea This function should accept the rectangles length and width as arguments and return the rectangles area. The area is calculated by multiplying the length by the width.

displayData This function should accept the rectangles length, width, and area as arguments and display them in an appropriate message on the screen.

double getArea(double, double);

void displayData(double, double, double);

int main()

{

double length; // To hold the rectangle's length

double width; // To hold the rectangle's width

double area; // To hold the rectangle's area

// Call the getLength function to get the rectangle's length.

// Call the getWidth function to get the rectangle's width.

// Call the getAres function to calculate the rectangle's area.

// Call the displayData function to display the rectangle's data.
