Question

A piece of strings is \(30\) cm long. What will be the length of each side if the string is used to form:
(1) A square?
(2) an equilateral triangle?
(3) A regular hexagon?

Answer

(1)c Perimeter of square \(= 30\) cm
\(4 × side = 30\)
Side \(= 30 / 4\)
Side \(= 7.5\) cm
(2)Perimeter of an equilateral triangle \(= 30\) cm
\(3 × side = 30\)
Side = 30 / 3
Side = 10 cm
(3)Perimeter of a regular hexagon \(= 30 \) cm
\(6 × side = 30\)
Side \(= 30 / 6\)
Side \(= 5\) cm
