Answer:
Option D.
Step-by-step explanation:
The area of a rectangle is
\(Area=length \times width\)
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.
\(A_1=A_5=3 \times 2=6\)
Rectangle 2 and 4 are congruent with length 6 cm and width 3 cm.
\(A_2=A_4=6 \times 3=18\)
Length of width of rectangle 3 are 6 cm and 2 cm respectively.
\(A_3=A_6=6 \times 2=12\)
The total area of the figure is
\(A=A_1+A_2+A_3+A_4+A_5+A_6\)
\(A=6+18+12+18+6+12\)
\(A=72\)
The area of figure is 72 square cm. Therefore, the correct option is D.
