6/7, 12/14, 18,21, 24/28, 30/35, 36/42 in so on
        
             
        
        
        
Given:
The parallel sides of a trapezium are 28.7 cm and 22.3 cm.
The distance between parallel sides is 16 cm.
To find:
The area of a trapezium.
Solution:
The area of the trapezium is:

Where,  are parallel sides and
 are parallel sides and  is the vertical distance between the parallel sides.
 is the vertical distance between the parallel sides.
Putting  in the above formula, we get
 in the above formula, we get




Therefore, the area of the trapezium is 408 square cm.
 
        
             
        
        
        
√5 = 5^(1/2) 
Multiplying two number with the same base has as result a number with the same base and the sum of the exponents so:
1/2 + 3 = 7/2 
which means 
5^3 x 5^(1/2) = 5^(7/2)
