Answer:
8 1/8 inches
Step-by-step explanation:
P = 2 ( l+w)
l = 13 1/8
P = 42 1/2
Substitute the two values into the equation
42 1/2 = 2 ( 13 1/8 + w)
Change the mixed numbers to improper fractions
42 1/2 = ( 2 *42+1)/2 = 85/2
13 1/8 = ( 8*13+1) /8 =105/8
85/2= 2 (105/8+ w)
Divide each side by 2
85/2 *1/2= 2/2 (105/8+ w)
85/4 = (105/8+ w)
Subtract 105/8 from each side
85/4 -105/8 = (105/8-105/8+ w)
Get a common denominator
170/8 -105/8 = w
65/8 = w
Change back to a mixed number
64/8 + 1/8 = w
8 1/8
