<h3><u>Givєn</u> :</h3>
- Radius of the tent,r = 3.5 m
- Height of the tent, h = 8.4 m
<h3><u>To Find</u> :</h3>
- length of the cloth required.
<h3><u>Solution</u> :</h3>
According to the question,
Slant height, l = 

curved surface area = 


i.e., Area of the cloth is 101.11m²
Now, length of the cloth required = 


X^2 +6x -5 = 0
x^2 +6x = 5 . . . . . add 5
x^2 +6x +9 = 14 . . . add 9
(x +3)^2 = 14 . . . . . . write left side as square
x +3 = ±√14 . . . . . . . take the square root
x = -3 ±√14 . . . . . . . subtract 3
Selection C is appropriate.
