Answer:

88 cm

Step-by-step explanation:

The side of the square = 6 cm, so the shorter side of each rectangle = 6 cms.

The area of each rectangle =  36 *  1 1/3

= 36 * 4/3 = 48 cm^2

So the longer side of each rectangle = 48 / 6 =  8 cms

Therefore, the perimeter of the whole figure

=  4( shorter sides ) + 8(longer sides)

= 4*6 + 8*8

= 24 + 64

= 88 cm   (answer)
