In a golden rectangles we have:
l/w = (1 + √5)/2 ≈1.618
So,
25/w = 1.618
w = 25/1.618
w ≈ 15.451
Rectangle Area = lw
Rectangle Area = (25)(15.451)
Rectangle Area ≈ 386 cm^2

Formula for the area of a rectangle?
Length of a long side x length of a short side = area
Why does the area of a rectangle change?
if you change the side length the area will change. It is possible to change them and not change the area. For example make side twice and long and the other half as long. But in general, if you change the lengths of the sides the area of the rectangle changes.
What are some whole number pairs of side lengths of a rectangle that forms a golden rectangle?
it is 14
What is the area of a rectangle that is 3 times as long as it is wide?
If we express the shortest side as x, then the rectangle's length is 3x (as it is 3 times as long as its width).To find the area multiply the length and witdh together.x * 3x = 3x2The area of the rectangle would be 3x2.e.g if the width of the rectangle was 4, the area would be:3 x 42 = 48
How does quadrupling the side lengts of a rectangle affect the area?
rectangle area is width x height so if each side quadruples area changes by 16
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.

How do you find the area of a square if you know the area of the rectangle inside it?
Multiply the long side of the rectangle's length by itself.
How is the golden rectangle to the golden section?
The ratio of the shorter side of the rectangle to the longer side is the same as the ratio of the longer side to the sum of the two sides. And that ratio is the Golden section.
What does a golden rectangle have to do with phi?
phi is incorperated into the golden rectangle, because if you divide the longer side of the golden rectangle by the shorter sid, the answer will be phi.(1.168...)

What is the area of a rectangle 4.5m x 10m?
The area of a rectangle is the long side length multiplied by the short side length. In this case 10m x 4.5m = 45 square metres
