What is a golden rectangle?
A golden rectangle is a rectangle where the ratio of the length of the short side to the length of the long side is proportional to the ratio of the length of the long side to the length of the short side plus the length of the long side. It is said to have the "most pleasing" shape or proportion of any rectangle. The math is like this, with the short side = s and the long side = l : s/l = l/s+l Links can be found below to check facts and learn more. In ratio terms, the Golden Rectangle has a width/height ratio of 1.618/1.
What is the diagonal distance of a rectangle 84 inches wide by 85.5 inches long?

The legs of a right triangle are 12 and 16 inches long respectively What is the area of the triangle?
Lets work it out:- If the legs are 12 and 16 inches, then a rectangle of that size would be 192 square inches in area. As the the diagonal of the rectangle makes two equal triangles (of legs 12 and 16 inches), the area of one of these is half the area of the triangle - 192/2 = 96 square inches.

If seven 9 inch squares are placed end to end to form a rectangle. What is the distance around the rectangle they form?
Seven 9 inch squares placed end to end would form a rectangle that was still 9 inches wide but 7 x 9 = 63 inches long. The distance around such a rectangle would measure its perimeter. Two sides are 9 inches long and two sides are 63 inches long. The perimeter would be 63 + 63 + 9 + 9 = 144 inches.
In a golden rectangle if the top and bottom lines of the rectangle are each 3 and one half inches how long would the side lines of the rectangle be?
To make it a golden rectangle the sides should be in 1:0.618 ratio. Lets say your width is made of a + b. a and b are in golden ratio. THis gives a + b = 3.5 <---- equ 1 b = .618 a (because they are in golden ratio) substitute to equ 1 1.618a = 3.5 a = 3.5/1.618 = 2.163 b = 1.336 now you can construct your sides with a = 2.163 to have a golden rectangle
