Answer:
She worked 12 hours for the week 
Step-by-step explanation:
Given that :
Hours worked :
Mondays = 40 hours
Tuesdays = 8 hours
If 1/4 of regular hours was worked in a certain week, the number of hours worked that week can be calculated thus ;
1/4 (Monday hours + Tuesday hours)
1/4(40 + 8)
(1/4 * 40) + (1/4 * 8)
10 + 2 
= 12 hours
 
        
             
        
        
        
If the area of one is 20, that the area of 30 is 20*30=600 square inches.
