Answer:
The string length is the perimeter of the shape.
.. For each case, perimeter = 30cm
(i) Square
A square has all the side equal.
Perimeter 4x (side of square)
:- side of square perimeter =
[tex] \frac{perimeter}{4} = \frac{30}{4} = 7.5cm[/tex]
Hence, length of each side if the string is used to form a square will be 7.5 cm.
(ii) Equilateral triangle An equilateral triangle has three equal sides.
Perimeter = 3 × (side)
Hence, length of each side if the string is used to form an equilateral triangle will be 10 cm.
(iii) Regular hexagon
A regular hexagon has six equal sides.
Perimeter 6× (side)
:- side =
[tex] \frac{perimeter}{6} = \frac{30}{6} = 5cm[/tex]
Hence, length of each side if the string is used to form a regular hexagon will be 5 cm.
