A lake near the Arctic Circle is covered by a 2
22-meter-thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. After
3
33 weeks, the sheet is only
1.25
1.251, point, 25 meters thick.
Let
y
yy represent the ice sheet's thickness (in meters) after
x
xx weeks.

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
