OpenStudy (study312):

one of the things that always got me was that line showing the height in the middle of that triangle, I always thought it mean't there were two triangles

OpenStudy (study312):

meant*

OpenStudy (study312):

so what we will do is find the area of that rectangle, first 2 x 12

OpenStudy (study312):

can you tell me?

OpenStudy (anonymous):

24

OpenStudy (study312):

good, now the area of that big triangle, 5 x 12

OpenStudy (anonymous):

60

OpenStudy (study312):

now since it is a triangle we divide that by 2, so 60 รท 2

OpenStudy (anonymous):

30

OpenStudy (study312):

so finally 30 + 24

OpenStudy (anonymous):

54
