Answer:
The answer to your question is width = 6 ft; length = 24 ft
Step-by-step explanation:
Data
Area = 144 ft²
width = w
length = l
The width is 1/4 of the length
Formula
Area = width x length = w x l
Length = 4 width     l = 4w
Process
1.- Substitute length in the first equation
                        Area = w(4w)
Simplify 
                        Area = 4w²
2.- Solve for w
                       w = 
Substitution
                       w = 
Simplification
                       w = 
Result 
                       w = 6 ft
3.- Find l
                        l = 4(6)
                        l = 24 ft

Good afternoon, 
x= first odd integer 
x+2 = second odd integer
x+4= third intenger
The sum of the trhree integer is 195, so:
x + (x+2) + (x+4) = 195
3x = 195 - 4 - 2
3x=189
x= 63
Then the Answer is: 63, 65 and 67
