by : $105$

 * The Squares of Veneer
 * A man has two squares of valuable veneer, each measuring $25$ units by $25$ units.
 * One piece he cut, in the manner shown in our illustration, in four parts that will form two squares,
 * one $20$ units by $20$ units, and the other $15$ units by $15$ units.
 * Simply join $C$ to $A$ and $D$ to $B$.

 * How is he to cut the other square into four pieces that will form again two other squares, with sides in exact units,
 * but not $20$ and $15$ as before?
