#21. A golden rectangle has a length to width ratio called the golden ratio, which approximately 1.62.

a) Which of the following dimensions of rectangles are examples of golden rectangles?

• 24 m x 38.9 m = 1.62 Golden rectangle

• 52 cm x 120.5 = 2.31

• 348 mm x 565 mm = 1.62 Golden rectangle

I got the answers NOT by multiplying the length and width but by dividing the length by the width.

b) If the width of a golden rectangle is 6.4, what is it's length? Give your answer to the nearest tenth of a metre.
