IF QP=25 , MN=35, and SR= 13, calculate the area of triangle LMN

as the triangle is intercepted by the lines QP and base MN both are which parallel.they divide in the ratio 5:7.solve the problem on same lines

OpenStudy (anonymous):

A)796.3 B)227.5 C)437.5 D)568.8

k so these are the options u got to choose from.

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

i got a) option as answer.Is it right?

OpenStudy (anonymous):

not sure, but i will find out later thanks for the help

OpenStudy (anonymous):

how i come it: as i told u the line divide the triangle in 5:7 ratio (23:35) as they are parallel(its a theorem)owing to this fact the line SR=13 is of 2 units(7-5) and LR of 7 units which is nothing but altitude.then using area formula= 0.5*base*altitude i got 0.5*35*91/2 = option a
