Can a 11 year old weigh 79 pounds?

of course an 11 year old girl can weigh 79 pounds! I'm 11 and my weight was 79 pounds after my growth spurt. Before that I was even less! I'm the average height for my age, and I know that I'm under-weight. It all depends on height, but of course an 11 year old girl is able to weigh 79 pounds.
