A girl made a loop out of variously sized pieces of 3 cm wide ribbon. The outer circumference of the loop measured 122 com, while the inner one measured 78 cm.
What was the area of the original ribbon in square centimeters if none of the pieces overlapped?
This puzzle may seem much more difficult than it really is.
Sew far sew good!
The answer is 300 sq cm.
It's easy to find out the area by adding the lenghts of the inner and outer edges, dividing that by two, and then multiplying the resul by three.
