Answer:
Area after 7 folds = 0.73 inch²
Step-by-step explanation:
After 1 fold width or length reduces to half.
Area = Length x width
So after 1 fold area will reduce to half.
So we have
[tex]\texttt{Area after n folds =}\frac{\texttt{Initial area}}{2^{\texttt{number of folds}}}[/tex]
Initial area = 8.5 x 11 = 93.5 inch²
Number of folds = 7
[tex]\texttt{Area after 7 folds =}\frac{\texttt{Initial area}}{2^{7}}\\\\\texttt{Area after 7 folds =}\frac{93.5}{128}=0.73inch^2[/tex]
Area after 7 folds = 0.73 inch²
