draw a line EB now its split into a triangle and a trapezoid. area of the triangle = 0.5 * base * height area of the trap ezoid = (height/ 2) * sum of the parallel sides
Aizhalee
  • Aizhalee
I sure did , only welshfella is being nice to reply
anonymous
  • anonymous
im was trying to figure it out sorry
Aizhalee
  • Aizhalee
Ok Thank you welshfella I now see the formula used to solve the area , do i use the coordinates ?
Aizhalee
  • Aizhalee
Its ok
anonymous
  • anonymous
you use the boxes to count the length of a side
welshfella
  • welshfella
count the lines to find the length base of triangle = 10 and height = 3
anonymous
  • anonymous
so 3 boxes would mean the side is 3 lengths long
welshfella
  • welshfella
yea
Aizhalee
  • Aizhalee
ohhh Ok I see I see . :)
anonymous
  • anonymous
so for the triangle you would do 3x4=12/2=6
Aizhalee
  • Aizhalee
so from the height of the trapezoid is 6 and the base is 7
anonymous
  • anonymous
then the other triangle would be 6x3=18/2=9
welshfella
  • welshfella
area of trapezoid = (6/2) * (6 + 7) = 3 * 13 = ?
Aizhalee
  • Aizhalee
Ok quick question where was the four from ? from 3*4=12
anonymous
  • anonymous
i split the big triangle in half and got two smaller triangles
Aizhalee
  • Aizhalee
3*13 is 39
welshfella
  • welshfella
oh right you are doing it a different way from me
Aizhalee
  • Aizhalee
o.o
anonymous
  • anonymous
ya, im just spliting the triangles in half to make it easier for me
welshfella
  • welshfella
right so thats the area of the trapezoid the area of triangle AFB is 1/2 * 3 * 10 = ?
Aizhalee
  • Aizhalee
15
anonymous
  • anonymous
yes
welshfella
  • welshfella
ok so finally total area = 39 + 15 = 64
anonymous
  • anonymous
:D

  • Aizhalee
Wow , Thank you both so much ♥ I really appreciate it :D . and sorry lucas for being a bit rude for untagging you . God bless and take care
