#4 2/3# inches

Area if rectangular =length x width

#30 1/3 = 6 1/2 * width#

#91/3 =13/2 * width#

#91/3 * 2/13 = # width

#14/3 = 4 2/3 =# width.

The width is #4 2/3# inches.

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
