Rearrange the formula to make l the subject:
S = n/2 (a+l)

For a right angled triangle, square of the hypotenuse (h) is equal to the sum of squares of its other two sides (p, b). b = 3. b = 8. l = 10, a = 2, n = 5.

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
