On a graph sheet, using a scale of 2cm to 2 units on both axes, (a) Draw the straight line joining points P(-5, 3) and Q(2, 3); (b) construct the locus L of points equidistant from P and Q; (c) by construction, locate points R and S on L, such that PRQS forms a rhombus of sides 5cm; (d) find : (i) coordinates of R and S; (ii) area of the rhombus in cm\(^{2}\).
