Answer:
Length = 5 
Width = 21
Step-by-step explanation:
(x)(x + 16) = 105 
x^2 + 16x = 105 
x^2 + 16x - 105 = 0 
(x - 5) x ( x + 21) = 0
x - 10 = 0 
x = 5
x + 21 = 0 
x = -21
Now that we have the zeroes. 
We have to find the most viable one to put in.
Using -21 would not make sense, so we will use 5. 
Plug it in: 
x = 5 
(5) (5 + 16) = 105 
5 ( 21) = 105

Answer:
    __X__l__Y_
         1     l    3
         5    l    6
         9     l    9
         13   l    12
         17   l    15
         21   l    18
On the right side, the numbers get larger by adding three each time. On the left side, the numbers get larger by adding 4 each time. It would be the same for any other pair of numbers when you add 4 to the left, and 3 to the right. For instance, the next pair would be (25 , 21). 25 would be the X value, and 21 would be the Y value.
