Keep reciving error C2064, why?

I keep getting this error when building my code. error C2064: term does not evaluate to a function taking 1 arguments.

#include<iostream>
#include<cmath>
using namespace std;
double areaFunction(double,int,int,int);
int perimeterFun(int,int,int);
 
void main()
{
    int side, side2, side3, perimeter;
    double semi, area;
    cout<<"Enter the side of a triangle ";
    cin>> side;
    cout<<"Enter the side of a triangle ";
    cin>> side2;
    cout<<"Enter the side of a triangle ";
    cin>> side3;
 
    if(side + side2 > side3 && side2 + side3 > side && side + side3 > side2)
    {
        semi =(side + side2 + side3)/ 2.0;
        area = areaFunction(semi,side,side2,side3);
        perimeter = perimeterFun(side,side2,side3);
 
        cout<<"The area of the triangle is "<<area<<endl;
        cout<<"The perimeter of the triangle is "<<perimeter<<endl;
 
    }
    else
        //Triangle is illegal
        cout<<"These side values produce an illegal triangle."<<endl<<endl;
 
}
double areaFunction(double semi,int side,int side2,int side3)
{
    return sqrt(semi(semi-side)(semi-side2)(semi-side3));    
}
int perimeterFun(int side,int side2,int side3)
{
    return side + side2 + side3;
}
 

For the life of me I can't see what's wrong.

have you missed the * operators in the sqrt() expression?, e.g.

double areaFunction(double semi,int side,int side2,int side3)
{
    return sqrt(semi*(semi-side)*(semi-side2)*(semi-side3));    
}

Yes, I now feel very stupid. Thanks you for seeing that.
