Question 314121
if the long side of a golden rectangle is 26 cm, what is the area ?
.
Golden ratio: {{{(1/2)(1+sqrt(5))}}}
Let w = width
then
{{{(1/2)(1+sqrt(5))w = 26}}}
{{{ (1+sqrt(5))w = 52}}}
{{{ w = 52/(1+sqrt(5))}}}
{{{ w = 16.07 }}} cm
.
Therefore the area is
width*length = 16.07*26 = 417.8 cubic cm
