Step-by-step explanation:
1234, 1243, 1324, 1342, 1432, 1423, 2134, 2143, 2314, 2341, 2413, 2431, 3214, 3241, 3124, 3142, 3412, 3421, 4321, 4312, 4231, 4213, 4132, 4123
(15c-11 )(c-1)
you should try different numbers their multiplication be 11 and then check if they produce -26...
1.3 million
The ratio of length to breadth is 3:4
let the length be 3x
breadth be 4x
area = 4x x 3x
6912 = 12x^2
x^2 = 576
x=24
length= 72
breadth =96
actually length will be greater than breadth
so the ratio must be 4:3 then alter the above length and breadth values
