Answer:
Option D.
Step-by-step explanation:
The area of a rectangle is
[tex]Area=length \times width[/tex]
In the given net we have 6 rectangles with three pairs of congruent rectangles.
Rectangle 1 and 5 are congruent with length 3 cm and width 2 cm.
[tex]A_1=A_5=3 \times 2=6[/tex]
Rectangle 2 and 4 are congruent with length 6 cm and width 3 cm.
[tex]A_2=A_4=6 \times 3=18[/tex]
Length of width of rectangle 3 are 6 cm and 2 cm respectively.
[tex]A_3=A_6=6 \times 2=12[/tex]
The total area of the figure is
[tex]A=A_1+A_2+A_3+A_4+A_5+A_6[/tex]
[tex]A=6+18+12+18+6+12[/tex]
[tex]A=72[/tex]
The area of figure is 72 square cm. Therefore, the correct option is D.
