|Given are two fence designs. Both are available for arbitrary value of x. Now
the density of a fence is defined as the total length of the wire per
square meter. It measures how expensive the fence is. The coarseness of a
fence is the length of the longest straight line you can find inside the fence
plane intersecting the wire only at the two endpoints.
|If you look at the two designs, both for coarseness 10cm, which one has the smaller density?|
