Problem #3
raul measured himself to be 54 inches tall. when he was at the doctor, he was actually
measured at 55 inches. approximately what percent error was raul's measurement? circle

He was probably measuring himself without shoes on so with shoes it adds a inch to his Highth

Hope this helps in some way

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

+2+=+%2836%2fx%29%5e2+

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
