area of triangle pqr=area of triangle pQf+area of triangle prf

"four triangle is give find other two "
u mean
30.30,40,84 are triangle areas ?
ganeshie8 (ganeshie8):
yes
OpenStudy (ikram002p):
and is it givven what is O ?

dont know
OpenStudy (anonymous):
i think it divides in the ratio1:2
OpenStudy (ikram002p):
i think it well be like a trick :D
84+PEO+DOQ=35+30+40
40+4+QOD=30+35+EOP
OpenStudy (anonymous):
i think qre=drq
OpenStudy (ikram002p):
well if area of PEO=x
and area QOD=y
then
40+84+y=30+35+x
x+y+84=35+30+40
two linear equation

@ikram002p are you assuming the given segments are medians ?
OpenStudy (ikram002p):
nope
OpenStudy (ikram002p):
i only assumed that area is coversative
ganeshie8 (ganeshie8):
`84+PEO+DOQ=35+30+40`
how did u get this ?

i think triangle rdp/triangle dop=2/1 ratio
OpenStudy (ikram002p):
got what i did nw @ganeshie8 ?
ganeshie8 (ganeshie8):
how can both the triangles have equal area ?

wait lol
my bad
ganeshie8 (ganeshie8):
\(\large 84 + x + y \ne 40 + 30 + 35 \)
OpenStudy (ikram002p):
yes yes , sorry
ganeshie8 (ganeshie8):
instead we can use ratios of areas to solve this
