Berlin Papyrus 6619/Examples/Problem 1/Historic Proof

Proof
The method of solution used is the rule of false position.

Assume that:

But the result should be:
 * $100 = 64 \times \paren {1 + \dfrac 9 {16} }$

Therefore, our two squares must be $64$ times bigger.

Therefore their sides must be $8$ times bigger.

So the result is:
