The length of a rectangle is six times its width. If the perimeter of the rectangle is 126cm , find its area.

The area = 486 cm^2

The length is 54 cm and the width is 9 cm

54 times 9 = 486

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
