Will give BRAINLIEST BRAINLIEST BRAINLIEST to correct answer

38.4 m

First, you have to multiply all the sides' sum by 0.8, which is the same thing as 4/5.

Add all the sides. 16+12+20=48. 48*4/5=38.4

I need 10 brainliests so please give me 1.

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
