Understanding the Blob Pythagorean Theorem

A king consults his counsellor on dividing his land among his daughters. The counsellor explains concepts of scaling and similarity, and introduces the 'blob Pythagorean theorem' to solve the king's problem. The king learns that similar shapes maintain proportional areas, and the theorem applies universally to all similar shapes. The counsellor demonstrates the theorem using right-angled triangles, and the king reflects on the moral of the story.

What shape is the piece of land that the king decides to keep for himself?

• A circle

• A square

• A rectangle

• A right-angled triangle
