What is the area of the figure? A rectangle is cut out of a large rectangle. The larger rectangle has a base of 6 yards and height of 7 and one-fourth yard. The smaller rectangle inside has a base of 3 and two-thirds yard and height of 5 yards.

Small one: 18 and 1-thirds yards²  Large one: 43.5 yards²

Step-by-step explanation:

Area of rectangle= base*height

Large one: base = 6, height= 7.25 (7 and 1-fourth)

Area= 43.5yards²

Small one: base = 3(2/3 or 2-thirds), height= 5

change the mixed fraction 3(2/3) to 11/3

area= 11/3 * 5 = 55/3

change to mixed fraction which = 18(1/3)

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.
