You can put this solution on YOUR website!
if the long side of a golden rectangle is 26 cm, what is the area ?
.
Golden ratio: %281%2F2%29%281%2Bsqrt%285%29%29
Let w = width
then
%281%2F2%29%281%2Bsqrt%285%29%29w+=+26
+%281%2Bsqrt%285%29%29w+=+52
+w+=+52%2F%281%2Bsqrt%285%29%29
+w+=+16.07+ cm
.
Therefore the area is
width*length = 16.07*26 = 417.8 cubic cm
