Detailed Solution

A piece of string is 30cm long. The length of each side if the string is used to form an equilateral triangle is 10 cm.
An equilateral triangle is a three-sided with all sides equal in length.
Let the length of each side be ‘a’. Then perimeter = 3a
The total length of the string will be the perimeter of the triangle. So,
⇒3a = 30
⇒a =10 cm
Therefore, the required integer is 10.
