Step-by-step explanation:
Length of old is x inches. 
Because it is square we have that area of the old canvas : 
When we read : width of new is increased by 8 so : x+8
Length is x.
The difference of areas:
Old canvas : A1=
New canvas : 
Now we can find A2-A1:

 
        
             
        
        
        
469 603 divided by 9 = 67 67x 7 = 479

Answer:
He will read 92 pages in an hour going by the current rate at which he reads 
Step-by-step explanation:
The complete question is as follows;
Jamil found that he reads 1/5 of his 115 - page book in 1/4 of an hour. At this rate how many pages does he read in an hour
We proceed as follows;
If he reads 1/5 of 115 in 1/4 hour
1/5 of 115 pages refer to 1/5 * 115 = 23 pages 
This means that he reads 23 pages in quarter of an hour 
So in an hours the number of pages he will read will be 23 * 4 = 92 pages 
 
        
             
        
        
        
It rlly does do the expression is 0.2^w
