have you tried cutting it up into peices then solving each piece and adding it up at the end
anonymous
  • anonymous
yup i have but i'm just not sure its the right answer
anonymous
  • anonymous
for the area i got 143,992 ft but i'm not totally sure thats right..

  • anonymous
ahhh i see well if i could see the process i could check your math

|dw:1328578695789:dw| (all the triangles are equal) so i divided 328 in half to get the one side. the other side i subtracted 550-328, then divided it by 2

then i just did normal area for a triangle 1/2BH and so A=1/2(164)(111) for the square, i just did base times height, so 328x328 i added those two together and got my area

looks good to me.

well could you maybe try it without using my work? just to see the answer u get
anonymous
  • anonymous
did you get 125,788?
anonymous
  • anonymous
nope, i got 116,686 for some reason...

  • anonymous
welll did you multiply the area of the triangle by two? that way your not adding one triangle to the area of the rectangle your adding the area of both triangles
anonymous
  • anonymous
no i didnt! okay, now i got the same answer as u!
anonymous
  • anonymous
ok good :)

  • anonymous
alrightyy! i'll probably look dumb asking this but..... okay how do u get that area of 125,788 ft to be 10% and 20% larger?
anonymous
  • anonymous
you could multiply the area by .1 and .2 then add that to answer to the area
