A piece of string is 36 cm long. What will be the length of each side, if it is used to form: a. A square b. A triangle with all sides of equal length c. A hexagon (a six sided closed figure) with sides of equal length?
(a)
Answer
Each side of the square = 9 cm
(b)
Answer
Each side of the equilateral triangle = 12 cm
(c)
Answer
Each side of the regular hexagon = 6 cm
Explanation
(a) For a square with 4 equal sides: side = perimeter ÷ 4 = 36 ÷ 4 = 9 cm. (b) For an equilateral triangle with 3 equal sides: side = perimeter ÷ 3 = 36 ÷ 3 = 12 cm. (c) For a regular hexagon with 6 equal sides: side = perimeter ÷ 6 = 36 ÷ 6 = 6 cm.
