Answer:

The possible arrays are: (1,28) , (2,14) , (4,7)) , (7,4) , (14,2) and (28,1)

Step-by-step explanation:

Here, the total number of solar panels to be installed  = 28

Let  us assume the installed array has m rows and n columns.

Now, the total panels installed = Number of rows x Number of columns

or, 28 = m n

The following cases are possible for array:

(a) When  m = 1, n = 28  (as m x  n = 28)

So, here array has 1 row with 28 columns.

(b) When  m = 2, n = 14  (as m x  n = 28)

So, here array has 2 row with 14 columns.

(c) When  m = 4, n = 7  (as m x  n = 28)

So, here array has 4 row with 7 columns.

(d) When  m = 7, n = 4  (as m x  n = 28)

So, here array has 7 row with 4 columns.

(e) When  m = 14, n = 2  (as m x  n = 28)

So, here array has 14 row with 2 columns.

(f) When  m = 28, n = 1  (as m x  n = 28)

So, here array has 28 row with 1 columns.
