Answer:
Area of ABCDEFG = area of triangle ABC
+area of rectangle AGHC
+ area of rectangle FDIH
+area of triangle FED
Step-by-step explanation:
Area of triangle ABC:
= 1/2*12*5
=6*5
=30cm^2
Area of rectangle AGHC:
= 12*(25-4)
=12*21
=252cm^2
Area of triangle FDIH:
=4*(12-4)
=4*8
=32cm^2
Area of triangle FED:
=1/2*(12-4)*2
=12-4
=8cm^2
Thus area of ABCDEFG = 8+32+252+30
=322cm^2
