Heron's formula is named after Hero of Alexendria, a Greek Engineer and Mathematician in 10 - 70 AD. You can use this formula to find the area of a triangle using the 3 side lengths.
Therefore, you do not have to rely on the formula for area that uses base and height. The picture below illustrates the general fro mu la where S represents the semi-perimeter of the triangle ,
        
                    
             
        
        
        
so from 190.1 to 201.5 is 201.5 - 190.1 = 11.4.
now, if we take 190.1 as the 100%, what is 11.4 off of it in percentage?

 
        
                    
             
        
        
        
Step-by-step explanation:
x2-8x-3x+24=0
x(x-8) 3(x+8)
(x-8)(x+8)
x-8=0 or x+8=0
x=8. x= -8
