Answer:The answer to the question is;

The area of hexagon is 136.

Step-by-step explanation:We have area ABR = 0.5 (ABC+ABD) since R = midpoint of segment CD

Similarly we have area BCS = 0.5 ( BCD+BCE)

also area CDT = 0.5(CDE+CDF)

DEU = 0.5(DEF+DEA)

EFP = 0.5(EFA+EFB) and

FAQ = 0.5(FAB+FAC)

However 0.5 (ABC+ABD) + 0.5 ( BCD+BCE)+0.5(CDE+CDF)+0.5(DEF+DEA)+

0.5(EFA+EFB) + 0.5(FAB+FAC) = 0.5*6*0.5 * Area of a regular hexagon

= 3/2×area of the hexagon = 12+34+56+12+34+56 = 204

Area of the hexagon = 2/3*204= 136
