    The width of the top is 9+11.5=103.5m

    the sloped sides are 7m

    the depth is 5m

    if you form a triangle at the side. =7^2=5^2+x^2

    49=25+x^2>>24=x^2>>x=4.9>>2*4.9=13.8m

    Bot=103.5-13.8=93.7m.

    Assuming this is a side view of lake, and the top is 9*13.5 m, depth is 5m, sloped side is 7m:

    Each side section is a triangle h=5, hypotenuse 7, so subtract 2*base

    w = 121.5 - 2√(49 -25) = 111.7 m
