X and Y are two points respectively on sides AB and AC of triangle ABC such that XY is parallel to BC. If the ratio of area of triangle ADE to that of the trapezium XYCB is 25:144 and BC=13 cm, then find the length of XY.	Choose the correct option
A) 12	B) 13	C) 14	D) 11	E) 5
ABC and AXY are similar triangles.   So (side of ABC/side of AXY)^2=169/25   side of ABC/side of AXY = 13/5   So the length of XY = 5   Answer - 5
<result>E</result>
X and Y are two points respectively on sides AB and AC of triangle ABC such that XY is parallel to BC. If the ratio of area of triangle ADE to that of the trapezium XYCB is 25:144 and BC=13 cm, then find the length of XY.
