width of cloth = 1.1m
& h of conical tent = 12m
and base r = 16m
so
 {l}^{2}  =  {r}^{2}  +  {h}^{2}  \\  {l}^{2}  =  {16}^{2}  +  {12}^{2}  \\  {l}^{2}  = 256 + 144 \\  {l}^{2}  = 400 \\ l = 20

so csa of cone=
\pi \times r \times l \\  = 3.14 \times 16 \times 20 \\  = 1004.8
so lenght of cloth
1004.8 = l \times 1.4 \\ 1004.8  \div 1.4 = l \\ 717.7 = l
