The area of a rectangle is 20 square units and its length is 5 centimeters. Find its perimeter

18 centimeters.

Step-by-step explanation:

Since you already know the length (height) divide 20 by 5 = 4.

This gives you the width (4), add up all the sides ( 4 + 4 + 5 + 5).

The sum comes out to be 18.

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
