base1=0
base2=0
height=0
area=0

print "Enter base1: ";
base1 = gets.chomp.to_i;  

print "Enter base2: ";
base2 = gets.chomp.to_i;  

print "Enter height: ";
height = gets.chomp.to_i;

area = 0.5 * (base1 + base2) * height;
    
print "Area of Trapezium is: ",area;

Output:

Enter base1: 3
Enter base2: 4
Enter height: 2
