It's sort of a common sense thing, honestly. How on earth can you apply a male adult's standard to a 13-year-old teenage girl?
BMI is used to estimate a person's healthy weight based on his or her (1) age, (2) height, (3) sex, and (4) weight. They had just completely ignored the "age" and "sex" factors.
============================
Anyway, she is . . . overweight.
(or fat, whatever you want to call it).
The normal range would be somewhere between 90 pounds and 140 pounds. At that age (13 years old) 90 to 115 pounds is good for an inactive girl; 115 to 125 is good for an active girl; 125 to 140 is good if you are really, really active, if you are not active, then it can be consider as overweight, too.
And NO, 147 pounds is definitely NOT the average weight for 13-year-old girls. 117 pounds in the average for 13-year-old girls--that's 30 pounds less.
These are just estimates. There is no medical recommended ranges for teens because healthy weight ranges of teens change with each month of age and as height increases.

The weight for a person 5'5-5'6 in tall:range(111 to 150 lb)
But if you and your friend are not really sure and need mor information, try calculating the weight and height or if she's really serious about this topic, she can ask her doctor.
