Geometry of the Dam:

Total height of the dam (H): 100 m
Width of the dam (B): 100 m
Upper width of the dam (  ): 10 m
Height from the top to the bottom of the upper width (  ): 12 m
Height from the bottom of the upper width to the ground level (  ): 88 m

Area of the dam cross-section = (1/2) * (upper width + lower width) * height
