Answer:
base radius of conical tent ⛺=(r) =7m
height of conical tent (h)=24m.
slant height of conical tent(l)=√r²+h²
=√7²+24²
=√49+576
=√625
=25m
Canvas required to making a conical tent
=CSA of conical tent
=πrl
=22/7×7×25
=550m²
let length of Canvas be =lm
area of rectangular Canvas=550m²
l×b=550
l×4=550
l=137.5
so length of canvas required to making conical tent=137.5m
