I need help!
In the following figure, ABC is a triangle with sides measuring 25 cm, AB = AC = 15 cm and BC = 20 cm.
And is quad BDEF a square.
In those circumstances, the measure in centimeters, square BDEF side is equal to?

this can't possibly be correct the way you've labeled things.
AC is the hypotenuse of a right triangle and thus
AC > BC, AC > AB

The intention is presumably that AC = 25 cm, AB = 15 cm and BC = 20 cm.
If BD = DE = x, DC = (20 cm - x) and x/(20 cm - x) = 15/20, so x = (60/7) cm.
