Paula completely covered a square wall using 87.5 R of wallpaper without any overlap. Which measurement is closest to the side length of this wall in feet? A 22 ft B 44 ft © Oft D 7 ft​

(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

i think it is 70
