How do you find the area of a triangle

A=1/2bh

Step-by-step explanation:

The area A of a triangle is given by the formula A=1/2bh where b is the base and h is the height of the triangle.

So for example if you got that the base of the triangle is 12 and the height is 14 you would plug it in like this:

A=1/2(12)(14)

A=6(14)

A=84

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
