Answer 1

Solution: Give the figure A D In above figure o's rectangle is contain two figure is and triangle. one 1 one الز In D ABED KCAB) = 1 CDE) ICBE) ICAD): a-c cis height of toiangle ABC. Now find the area of rectangle Area of Q ABED = Base x height: nx (a-c) Area or IABED -nca-c) Square unit 11) In A ABC Base FACAB)= . height=c Ź x Basex height I Area or AABC £xnxC unit - the square Area of AABC

then Area of figure AD EBC = Ared or DABED + Area or A ABC = n(-) +ļnc Area of the figure = nca-c) + Źnc square unit option ① is correct
