Osose is making a track so far the track is 8 1/2 meters long which is 2/3 of the length of the track he wants to create how long is the track when completed select all equations correct
8 1/2 . 2/3 = ?

2/3 . ? = 8 1/2

8 1/2 . ? = 2/3

8 1/2 ÷ 2/3 = ?

2/3 ÷ 8 1/2 = ?

8 1/2 . 3/2 = ?​

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
