Assume the following code is put in Rectangle.cpp, create the class declaration that would be put in Rectangle.h. Assume all data members are private and all function members are public.

#include "Rectangle.h"

Rectangle::Rectangle(double length, double width)

: mLength(length),

mWidth(width)

{

mArea = mLength * mWidth;

}

Rectangle::Rectangle()

: Rectangle(0.0, 0.0)

{

}

void setLength(double length) {

mLength = length;

mArea = mLength * mWidth;

}

void setWidth(double width) {

mWidth = width;

mArea = mLength * mWidth;

}

double getArea() {

return mArea;

}
