Q 11. A piece of string is 30 cm long. What will be the length of each side if the string is used to form :
(a) a square? (b) an equilateral triangle? (c) a regular hexagon?
Given that,
Length of the string is 30 cm
(a)For square,
Number of sides = 4
Therefore, Length of one side = 30 /4 = 7.5 cm
(b)For equilateral triangle,
Number of sides = 3
Therefore, length of sides = 30/3 = 10cm
(c) For a regular hexagon,
Number of sides = 6
Therefore, Length of one side = 30/6 = 5cm
