heyloooo re!! ;p
================================================================
Given,
BE = 9cm
CF = 12 cm
G is the centroid or the centre of the triangle,
its ratio will be 2:1
CG = 12 * 2/3 = 8cm
GF = 12 * 1/3 = 4 cM
Area of ΔBFC = 1/2 * 12 * 6 = 36 cm²
And, Area of ΔABC = 2 * Area of ΔBFC
= 2 * 36 cm²
= 72 cm²
the correct option is = (a) 72 cm²

hope it helps !! @_@
