Randall purchased a plot of land for his business. the figure represents a plan of the land showing the location of the office space, parking lot and open space for a yard so that the employees and visitors can enjoy time outside. the coordinates represent points on a rectangular grid with units in feet. what is the area of the plot of land that does not include the office space, the yard and the parking lot?

Option: A is the correct answer.

                 A) 3600 square ft.

Since, the area of the  plot of land that does not include the office space, the yard and the parking lot is:

The area of trapezium ABCD-Area of rectangle BCEF

As we know that area of trapezium ABCD is calculated by the formula:

Similarly length(l) of rectangle BCEF=130 ft.

and breadth or width(b) of rectangle BCEF=80 ft.

Hence, area of rectangle BCEF is calculated as:

       Hence, Required Area of Plot is:

          14000-10400

                 =3600 square ft.

what's that

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
