Hi,
Can someone please give a detailed explanation of the answer for this question? I am still unsure of the explanation given in the book. Thanks very much.

The area of triangle = 1/2*base*height
Base of triangle TR = TO - RO = c - 1
Height of triangle = Length of perpendicular drawn from S to base RT,
which is same as y-coordinate of point S i.e. b
Area = 1/2(c-1)(b). Choice B

RM is absolutely correct. The area formula 0.5*base*altitude is not only for a right angled triangle, but in fact is a general triangle area formula, which can be applied on all the triangles.RM:
Area = 1/2(c-1)(b). Choice B
