put vertical lines in to split it into a tranagle and 2 rectangles.
Find the areas and add them together.
I have deleted many of your questions.
People are not here to do all your homework for you.
Length of Ractangle (I) = 3 cm
Width of Rectangle (I) = 2 cm
Area of Rectangle ABCD = L * W
3 * 2 = 6 cm^2
=> Length of Rectangles (EFGC II) = 7 cm
Width of Rectangles (EFGC II) = 5 cm
Area of Rectangles (EGFC II) = L * W
7 * 5 = 35 cm^2
=> Triangle GHI
Base of Triangle = 9 cm
Height of Triangle = 11 cm
Area of Triangle = 1/2 * 9 * 11 [Area of Triangle 1/2 * b * h]
99/2 = 49.5 cm^2
Total Area of figure = 6 + 35 + 49.5 = 90.5 cm^2
