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.

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
