1)   If the area is 148 sq in., and the width is 20 in., we need to divide 148 by 20 to find the length...so we have

148/20 = 7.4 in

2) If 1cm = 70K   then 3cm would be 3*70 = 210K

3) To find the % increase use

(New - Old) / Old   = (4500-2900) / 2900 = about 55%

No....we don't get paid.....but donations ARE accepted......let me give you my address so you can send your check there.....!!!!  (just kidding.....)

1) LW=148

L20=148

L=148/20=37/5=7.4

2)   We already know that 1 cm = 70 km in this scale.  Three times as many centimeters would mean three times as many kilometers so 3cm=210 KM

3) an increase from 2900 to 4500 is an increase of 1600.  1600/2900=.55 (rounded to nearest hundredth) so this is about a 55% increase

I wish.

I'd shout you all an icecream if I was.

And I'd pay for you to have a holiday in  Australia so that you could collect your shout!

Does that sound good!

Kids can even bring their parents if the really want to!

Then I'd get to meet you all!
