    You can find the area of the 8, 10, 12 triangle using Heron's Formula, but there is not enough information to find the area of the other small triangle.

    8^2 + 11^2 IS NOT 12^2 who knows, maybe Pythagoras's theorem is WRONG....

    Yet it clearly shows the right angle symbol.

    All I can think of for the second triangle is that the line of length 8 bisects the larger triangle

    Or the 12cm side is a red herring and the "entire" other side length is 11cm.
