How to find the Area of a Square in a Triangle

How can we find the area of a square in a triangle without any numbers, just some information about some equal sides?
See how it's done in this video.

    Another alternative is to draw lines LJ and KM. Let their intersection point be N and note that triangles KHL, LNK and JNM are congruent (same base, same angles), their bases are parallel and are similar to the big triangle (same angles). ==> A = (2/3 |BD|)^2 = 4/9 (|BF|^2 + |FD|^2) = 4/9 (45 + 45) = 40

    Área del triángulo exterior =2*45=90 =2A+(A/4)=9A/4 ; A=40. Gracias y saludos.
