top=bottom=hexagon, side=6*ractangle

OpenStudy (caozeyuan):

now, hexagon can be divided into 6 triagnels, so top+bottom=12*trigangle

OpenStudy (caozeyuan):

base=5, height=4.3, so triagnle=5*4.3/2

OpenStudy (caozeyuan):

so top+bottom=5*4.3*6

OpenStudy (caozeyuan):

side =6*5*13

OpenStudy (caozeyuan):

now find those two values and add them up
