I'm trying to make a rectangle object and just do some simple commands. It has been a while since I've coded in c++ so I'm not sure what syntax errors I have? Any help would be appreciated

I'm getting the error:

request for member 'area' in 'c', which is of non-class type 'Rectangle*'

and the same error for perimeter as well

```
#ifndef RECTANGLE_H
#define RECTANGLE_H
class Rectangle
{
private:
float width;
float length;
public:
Rectangle(float width, float length);
~Rectangle();
float getWidth();
float getLength();
float area();
float perimeter();
float setWidth(float width);
float setLength(float length);
bool compareTo(Rectangle a,Rectangle b);
};
#endif // RECTANGLE_H
```

```
#include "Rectangle.h"
using namespace std;
int main()
{
Rectangle *a = new Rectangle(3,4);
Rectangle *b = new Rectangle(3,4);
a.area();
b.perimeter();
}
float width;
float length;
Rectangle::Rectangle(float l, float w)
{
setWidth(w);
setLength(l);
}
Rectangle::~Rectangle()
{
width = 0;
length = 0;
}
float Rectangle::getWidth()
{
return width;
}
float Rectangle::getLength()
{
return length;
}
float Rectangle::area()
{
return width * length;
}
float Rectangle::perimeter()
{
return width + length;
}
float Rectangle::setWidth(float W)
{
width = W;
}
float Rectangle::setLength(float L)
{
length = L;
}
bool Rectangle::compareTo(Rectangle a, Rectangle b){
if(a.length == b.length && a.width == b.width)
{
return true;
}
else
{
return false;
}
}
```
