2. Mary wants to construct a fence around her window garden. She measured the perimeter of
the garden to be 170 inches, but when she
arrived at the hardware store she discovered the
fencing was only sold by the foot. What is the
least amount of fencing, in feet, that Mary can
buy and still be able to completely enclose her
garden.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
