Evacuate Again! Ribbon Ring Vandal's Failure

Ribbon Ring is a weekly puzzle in Professor Layton and the Last Specter.

Puzzle

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?

Hints

What will you get if you add the inner and outer edges together?


Try to think about how long the original ribbon was.


Solution

Incorrect

Too bad!

This puzzle may seem much more difficult than it really is.

Correct

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.
