Draw perpendiculars OA and OB on RS and SM respectively. OR = OS = OM = 5 m. (Radii of the circle) In ΔOAR, OA2 + AR2 = OR2 OA2 + (3 m)2 = (5 m)2 OA2 = (25 − 9) m2 = 16 m2 OA = 4 m ORSM will be a kite (OR = OM and RS = SM). We know that the diagonals of a kite are perpendicular and the...

Draw perpendiculars OA and OB on RS and SM respectively.

OR = OS = OM = 5 m. (Radii of the circle)

In ΔOAR,

OA2 + AR2 = OR2

OA2 + (3 m)2 = (5 m)2

OA2 = (25 − 9) m2 = 16 m2

OA = 4 m

ORSM will be a kite (OR = OM and RS = SM). We know that the diagonals of a kite are perpendicular and the diagonal common to both the isosceles triangles is bisected by another diagonal.

∴∠RCS will be of 90° and RC = CM

Area of ΔORS =

Therefore, the distance between Reshma and Mandip is 9.6 m.
