<PRE><B>Question 240043</B>
you have a newspaper add 5cm x 12cm costing $1500.00
if you double the length how much will the add cost? 
i doubled the space of the ad which would cost $3000.00
then i doubled the length and came up with $2250.00
-------------------------------
If you double the length you will double the area of the add,
so $3000 seems like a reasonable cost.
--------
If you ALSO double the length you will multiply the area by 4.
So the cost should be 1500*4 = $6000
