Find the lenghts of parts of ABCD sides which are divided by the vertices of KLMN. If [the area of KLMN]: [area of ABCD] = 25:49

**Reiny**, Tuesday, June 9, 2009 at 9:11amyou will have 4 congruent triangles.

each will have legs of x and 7-x and a hypotenuse of 5

thus x^2 + (7-x)^2 = 25

solve as a quadratic, it factors nicely, and you should have sides of 3 and 4
