The perimeter of a rectangle is 24 in. and its length l l is 3 times the width w w . what is the length and width \left(l, w\right) ( l , w ) of the rectangle?

In a certain pentagon, the interior angles are a,b,c,d,e where a,b,c,d,e are integers strictly less than 180. ("strictly less than 180" means they are "less than and not equal to" 180.) if the median of the interior angles is 61 and there is only one mode, then what are the degree measures of all five angles?
