If the width (shorter length) of a golden rectangle is 1, then the length is . So for this situation, if the width is and 36 is the length,



Solve for x:



Now rationalize the denominator using the conjugate of , namely , so:



That's the exact answer. If you need a numerical approximation, use your calculator. However, round your answer to the nearest inch because you should never, unless specifically instructed otherwise, express an answer to a calculation involving measurements to a greater precision than the least precise given measurement. In this case, the length was expressed to the inch, so your answer must be to the nearest inch.
