The complete question in the attached figure
we know that
factor scale=1/13
factor scale=[dimension smaller rectangle]/[dimension original rectangle]
so
[dimension smaller rectangle]=[factor scale]*[dimension original rectangle]
a) for l=36 cm in the original rectangle
[dimension smaller rectangle]=[1/13]*[36]--------> 2.77 cm
b) for w=28 cm in the original rectangle
[dimension smaller rectangle]=[1/13]*[28]--------> 2.15 cm
c) [area smaller rectangle]=2.77*2.15------> 5.96 cm²

Your answer D. 8 is right; this is 
64, which we know is 3 because 4^3 is 64.
