Amy has a 55” television with a width of 72 cm and a height of 52 cm. Write two equivalent expressions for the area of her television screen.

Area = Length x width.

1st equation: Area = 72 x 52

2nd equation: Using distributive property by rewriting 52 as a sum of two numbers. 30 + 22 = 52

So now we get the second equation of:  72(30+22)

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
