Part b
8.
the home builder is now planning the size of a food pantry. the floor of the pantry will
have an area of 24 square feet and a perimeter of 20 feet.
what will be the length and width of the floor of the pantry?
a
width = 3 feet, length = 8 feet
width = 4 feet, length = 6 feet
width = 5 feet, length = 5 feet
width = 7 feet, length = 3 feet

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.

6e14 is the answer.
