Question

in parallelogram abcd find area of triangle abc if area of parallelogram abcd is parallogram ABCD,October is a point on AB. Find the area of the par allograft ABCD ,area of triangle ADC is 36 square cmand area of triangle BOC is a28 square cm.

Answer 1

Answer:

Step-by-step explanation:

In parallelogram ABCD , we have

Triangle DOC is 1/2 of parallelogram ABCD

= ar (AOD)+ar (BOC) =ar (DOC)

=36 sq.cm + 28sq.cm=ar (DOC)

=64sq.cm= ar (DOC)

Now,

ar (AOD)+ar (BOC)+ar (DOC)=ar (||gm ABCD)

= 36sq.cm+28sq.cm+64sq.cm= ar (||gm ABCD)

= 128sq.cm = ar (||gm ABCD)

.

. . Hence ar (||gm ABCD) is 128sq.cm
