If the ratio of the length to the width of a painting is "the golden ratio" ,
find the length, in feet, of a painting that has a width of 14 feet.
:
Let x = the length
:
%281%2Bsqrt%285%29%29%2F2 = x%2F14
Cross multiply
2x = 14%281%2Bsqrt%285%29%29
divide both sides by 2
x = 7%281%2Bsqrt%285%29%29
x = %287%2B7%2Asqrt%285%29%29
Using a calc
x ~ 22.652 feet is the length
