In triangle ABC, AB & AC intersect side DE of rectangle DBCE at F & G points. FG = 2, triangle ABC's perimeter is double of the perimeter of triangle AFG . If area of triangle ABC is 12 sq units, Then find the area of rectangle DBCE.

The area of triangle DBCE is also 12 sq units.

$F$ and $G$ are the midpoints of sides $AB$ and $AC$ respectively.So,$BC=4$ units.The height of triangle $ABC$ is $6$.
$\therefore$ $BD=CE=3$.$\therefore$ $(DBCE)=12$ square units
$\therefore$ $BD=CE=3$.$\therefore$ $(DBCE)=12$ square units
