Answer:
Area of the resulting rectangle = 23.375 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
![\texttt{Area after n folds =}\frac{\texttt{Initial area}}{2^{\texttt{number of folds}}}](https://tex.z-dn.net/?f=%5Ctexttt%7BArea%20after%20n%20folds%20%3D%7D%5Cfrac%7B%5Ctexttt%7BInitial%20area%7D%7D%7B2%5E%7B%5Ctexttt%7Bnumber%20of%20folds%7D%7D%7D)
Initial area = 8.5 x 11 = 93.5 inch²
Here the paper were folded completely in half, length is reduced to half and width reduced to half, that is
Number of folds = 2
![\texttt{Area after 2 folds =}\frac{\texttt{Initial area}}{2^{2}}\\\\\texttt{Area after 2 folds =}\frac{93.5}{4}=23.375inch^2](https://tex.z-dn.net/?f=%5Ctexttt%7BArea%20after%202%20folds%20%3D%7D%5Cfrac%7B%5Ctexttt%7BInitial%20area%7D%7D%7B2%5E%7B2%7D%7D%5C%5C%5C%5C%5Ctexttt%7BArea%20after%202%20folds%20%3D%7D%5Cfrac%7B93.5%7D%7B4%7D%3D23.375inch%5E2)
Area after 2 folds = 23.375 inch²
Area of the resulting rectangle = 23.375 inch²

Answer:
RS=13
Step-by-step explanation:
RS+ST=RT
2w+1+w-1=18
3w=18
w=6
RS= 2w+1= 2(6)+1= 12+1= 13
