Question
Length of a side of an equilateral triangle and its perimeter vary inversely with each other.
Options
True
False
Solution
This statement is False.
Explanation:
Length of a side of an equilateral triangle and its perimeter vary directly with each other, e.g. Let a be the side of an equilateral triangle.
So, perimeter = 3 × (Side) = 3 × a = 3a.
So, if we increase the length of side of the equilateral triangle, then their perimeter will also increases.
