Answer:
110m
Step-by-step explanation:
Hey,
we know that the radius of tent is 7 cm
and, height=24m
Then first we found l=,root under 7square + 24 square,we get,
25m=l
area of the curved surface = πrl
22/7×7×25=550m2 thus, the area of clothes = 550m2.
length of cloth required =area/width
= 550/4
= 137.5m
