How much should a ten year old weigh if her height is four feet tall and seven inches?

.

As per BMI it should be within18.5-24.9. If considering 4 feet 7 inches in meters,then it should be:(4x12)+7=55x2.54cm=1.397 met,

approx.x/1.4x1.4=20,x=39.2kg(asB.m.i=weight in kg/heightin metxmet,assuming b.mi is20).So in this case it should be39.2kgs.
