their goal?

Step-by-step explanation:

You need to analize the information provided.

You know that the goal is 40,000 laps over 4 weekends.

Knowing that  the teams swam 8,597 laps, 11,065 laps, and 9,211 laps over threee weekends, you need to add them in order to calculate the total number of laps the team swam over this three weekends.

Then:

Finally, in order to calculate the number of laps the team need to to swim the fourth weekend to reach their goal, you must subtract 40,000 laps and 28,873 laps. Then:

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
