Answer:
Step-by-step explanation:
L = 3*w + 1                      Given
P = 2*(L + w)                   Formula for Perimeter. Substitute for L     
P = 2*(3w + 1 + w)           Combine
P = 2*(4w + 1)                   
P = 58                             Given
58 = 8w + 2                    Remove the brackets
58 - 2 = 8w                     Subtract 2
56 = 8*w                         Divide by 8
56/8 = w 
7 = w
================
Find L
L = 3*w + 1
L = 3*7 + 1
L = 22
================
Check 
2L + 2W  = 58
2*22 + 2*7 =? 58
44 + 14 = ? 58
58 = 58
The answer checks.
