Area of Rectange, Right Angled Triangle and Circle

PROBLEM :

Calculate the area of rectangle, right angled triangle and circle.

Input:

The first line of the input contains T denoting the number of testcases. Then follows the description of testcase. Each testcase contains 5 space separated positive integers denoting the length of rectangle, width of rectangle, base of right angled triangle, perpendicular of right angled triangle and radius of circle respectively.

Output:

For each testcase, output a single line containing 3 space separated integers denoting the area of rectangle, area of right angled triangle, and area of circle respectively.

Note: We need to print the floor values of the areas. Also take value of pi = 3.14

Constraints:

1<=T<=50

1<=length / breadth / base / perpendicular / radius  <= 100

Example:

Input:
1
32 32 54 12 52

Output:
1024 324 8490

cin>>t ;
while(t--)
{
   cin>>RecL>>RecW ;
   cin>>TriB>>TriP ;
   cin>>CirR ;
 
   // area of rectangle
   cout<<RecL*RecW<<" " ;
 
   // area of traingle
   cout<<floor(0.5*TriB*TriP)<<" " ;
 
   //area of circle
   cout<<floor(3.14*CirR*CirR)<<" " ;
 
   cout<<endl ;
}
return 0;
}
