PQRS is a square with X and Y as the mid-points of sides PQ and PS respectively. The ratio of the areas of triangles YSR and XYR is :
(A). 3/2 (B). 1/3 (C). 2/3 (D). None of these

Use Pythagorastheorem to find base and height of the triangle YRX.

@- Ali Hasan- you are correct. We have to use mid point theorem,
