HEY BUDDY.......
HERE IS UR ANSWER...........
AREA OF PARALLELOGRAM = AREA OF TWO TRIANGLES OBTAINED WITH DIAGONAL
BUT A DIAGONAL DIVIDES A PARALLELOGRAM IN TWO TRIANGLES OF EQUAL AREA
SO, AREA OF A TRIANGLE =
BY HERON'S FORMULA
SEMI PERIMETER = 50+40+20/2 = 110/2 = 55cm
SO, AREA = ✓55(55-50)(55-40)(55-20) = ✓55×5×15×35 = 25✓231 cm^2
SO, AREA OF PARALLELOGRAM = 25✓231+ 25✓231 = 50✓231 cm^2 = 760cm^2 (approx)
