Given that:-

• Length of string= 30cm

To find:-

• The length of each side of the string is used

to form a square?

• The length of each side of the string is used
• to form an equilateral triangle?

• The length of each side of the string is used
• to form a regular hexagon.

Answer:-

$\bold{STEP-BY-STEP-EXPLANATION}$

Perimeter of square = 30 cm

4 × side = 30

Side = 30 / 4

Side = 7.5 cm

Perimeter of an equilateral triangle = 30 cm

3 × side = 30

Side = 30 / 3

Side = 10 cm

Perimeter of a regular hexagon = 30 cm

6 × side = 30

Side = 30 / 6

Side = 5 cm

Therefore,

Side of square = 7.5cm

Side of equilateral triangle = 10cm

Side of regular hexagon = 5cm
