Number of Seats
225
315
Number of Rows
4
5

Seats: 180, 225, 315, 405

Rows: 4, 5, 7, 9

Step-by-step explanation:

225 divided by 5 is 45, if you multiply the number of rows by 45, then you will get the number of seats.

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
