The perimeter of a rectangle is all sides added up, so length + length + width + width.
L = length
W = width
then the perimeter is L+L+W+W, or 2L + 2W, or 2(L+W).

what's the length? well, is just
2(27).
We want to solve
4/7 = x/161
Cross multiply.
7x =(4)(161) = 644
Divide each side by 7.
x = 644/7 = 92
Answer: x = 92
