The array can be taken as the rows.
If we take the first side as the length denoted by L and the second side as breadth denoted by B.
Then the area can be obtained as
length × breadth
L× B
The total area of the quilt is 24 squares which can be obtained as follows
All squares arranged in a single row.
(r³-3 )× 1= 24
12 squares arranged in 2 rows.
(r²+3 )× 2= 24
8 squares arranged in 3 rows.
(r²-1 )× 3= 24
6 squares arranged in 4 rows.
(r²-3 )× 4= 24
3 squares arranged in 8 rows.
(r )× 8= 24
2 squares arranged in 12 rows.
(r-1 )× 12= 24
