i wonder if you can ration side/area with stuff.... let me see. tri: base 6, h 4, area 12 tri base 12, h 8 area 48 does 6/12 = 12/48 doesnt look like it does it....

Area = (top+bottom)h/2 17 = (top+6)h/2 34 = toph +6h 34 - toph -------- = 6 is a good start h

I wish I knew what you are doing, I am mostly ignorant of all this

6n =22 n = 22/6 = 11/3 Area = 11/3(top + 6)h/2 Area = 11(top)h/6 + 22h/2 Area = (11(top)h + 66h)/6 I wish I knew what I was doing too, but I wont tell me lol

it aint d, thats fer sure

thats a good start!

Area = (11(top) + 66)h/6 we can prolly use the two equations to calibrate for a top or height

gonna have to write it on paper; keep track of it better...

You did it! Are you pretty confidant? I have been learning how to do these types of problems in the meantime. Thanks!

(t+6)h ------ = 17 ; h and t dont really matter as long as they scale 2 so lets say h=1 t+6 --- = 17 2 t+6 = 34 t = 28 ; thats as good of a top as any other... so lets use it and scale the rest
amistre64
  • amistre64
scale 6 = 22 scale = 11/3 (11/3)(28+6) (1)(11/3) -------------------- = A 2 308 66 11 ---- + --- * -- 3 3 3 --------------- 2 3388 + 726 ----------- 9 --------------- 2 4114 ----- = A = 228.6 18

I just tried it out with h=3 to begine with and I get the same results in the end.... youre welcome :)
