The 4 in 64,781 has a thousands value. The 2 in 25,409 has a ten thousands value 1000 times 10 equals 10,000 so the answer is.....10 times greater.

A density curve is always on or above the horizontal axis. The area underneath a density curve is exactly 1. The area under a density curve and above any range of values is the relative frequency of all observations that fall in that range.
The area of this figure is 532m.
First you do the square which is 18 time 18 gets you 324m.
The for the first triangle you would do 18 times 16 then divide by 2 which is 144m.
For the last triangle you would do 16•8 div by 2 which will give you 64m.
Add them all up and you get 532m.
I don't know i can't see.
