a triangle pqr is divided into 6 parts of triangle .four triangle is give find other two

OpenStudy (anonymous):

OpenStudy (anonymous):

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

OpenStudy (ikram002p):

"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 ?

OpenStudy (anonymous):

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

ganeshie8 (ganeshie8):

@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 ?

OpenStudy (anonymous):

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 ?

OpenStudy (ikram002p):

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
