ar(PQRS) = \frac{1}{2} ar( ABCD )

Step-by-step explanation:

In rhombus ABCD by joining the mid points of the the rhombus rectangle  PQRS  is  formed

since rectangle is also a parallelogram

then,

AB║ CD

In parallelogram QCDS ,

\bigtriangleup SRQ and parallelogram SQCD are on the same base SQ and between the same parallel lines DC and  SQ

then ,

ar(\bigtriangleup SRQ ) = \frac{1}{2}  ar(QSDC) .....(1)

similarly

in parallelogram ASBQ

ar(\bigtriangleup PSQ ) = \frac{1}{2} ar(ABQS )...(2)

add eq (1) and (2)

we get

ar(\bigtriangleup SRQ )+ar(\bigtriangleup PSQ ) = [tex]\frac{1}{2} ar( QSDC) +  \frac{1}{2} ar(ABQS)

ar(PQRS) = \frac{1}{2} ar( ABCD )

hence proved .
