In the parallelogram ABCD, if EF passes through the intersection of diagonals o, ab = 4, ad = 3, the perimeter of quadrilateral BCEF = 9.6, the length of of of can be obtained

In the parallelogram ABCD, if EF passes through the intersection of diagonals o, ab = 4, ad = 3, the perimeter of quadrilateral BCEF = 9.6, the length of of of can be obtained

It is shown that the quadrilateral ABCD is a parallelogram, ab = CD, O is the diagonal intersection, OA = OC, it is easy to prove that △ AOF ≌ △ Coe, OE = of, CE = AF, if CE = x, then AF = x, FB = 4-x, OE = y, then EF = 2Y, from perimeter = 3 + X + 2Y + 4-x = 9.6, | y = 1.3, that is, of = 1.3
