  1. first of all, your triangle is not right-angled.
    The slopes are 7/6, -7/6 and zero
    None of these are negative reciprocals of each other, a condition for a right angle.

    But the area is easy to find
    Clearly the base ST = 12 units and the height from R to ST is 7

    So the area = 1/2 x 12 x 7
    = 42 units^2
