The ratio of the areas of two parallelograms is 4: 9. the perimeter of the smaller parallelogram is 20 units. what is the perimeter of the larger parallelogram?

30 units

Step-by-step explanation:

We are given that The ratio of the areas of two parallelograms is 4:9.

So, ratio of sides of parallelograms :

So, sides ratios is 2:3

We are given that The perimeter of the smaller parallelogram is 20 units.

Let the perimeter of the bigger parallelogram be x

So,

Thus the perimeter of the larger parallelogram is 30 units

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
