Answer:
The fencing Chaz used for the pen is 56.67 feet
Step-by-step explanation:
Fencing interprets to circumference
If the radius of the pen is 9 ft
circumference = 
= 2*(22/7)*9
= 396/7
= 56.67 ft
 
        
             
        
        
        
In rounding, a number must be 5 or more to round up, and 4 or less to round down.
To round up to 4.26 you would need a number between 4.255 and 4.264
4.258 and 4.261 are two examples

(2x+3)*4 is less than or equal to 10. For x, the number, you would get x is greater than or equal to -1/4.
        
             
        
        
        
Let the width be x.
Length is 8 feet more than width. Length = x + 8
Area = x(x + 8)
width increased by 4, that is,  (x + 4)
Length decreased by 5,    (x + 8 - 5) = (x + 3)
Area  = (x + 4)(x +3)
Area remains the same
x(x + 8) = (x+4)(x +3)
x² + 8x =   x(x +3) + 4(x +3)
 x² + 8x =   x² +3x + 4x +12
x² + 8x =   x² +7x +12        Eliminate x² from both sides
8x = 7x + 12
8x - 7x = 12
x = 12
Dimensions of original rectangle :  x,  x + 8
12, 12 +8 =   12, 20
Original rectangle is   20 feet   by 12 feet
