The width is #4 2/3# inches.

Explanation:

The area of a rectangle is calculated from:

#A = l xx w# but if you want the the width you have to change the subject to get:

#w= A div l#

#w= 30 1/3 div 6 1/2" "larr# change to improper fractions.

#w= 91/3 div 13/2" "larr# multiply by the reciprocal

#w = cancel91^7/3 xx 2/cancel13" :larr# cancel to simplify. #(91 div 13=7)#

#w= 14/3#

#w = 4 2/3# inches
