The area of the figure can be obtained by splitting the figure into smaller components
The area of the irregular figure = Area of A + Area of B + Area of C
Area of A = L X B = 12 x 7 = 84 sq meters
Area of B = L X B = 5 X 8 = 40 sq meters
Area of C = L X B = 5 x 8 = 40 sq meters
Total area = 84 + 40 + 40 = 164 sq meters
