The constant of proportionality (K ) we will write
Perimeter = 3 ( side) where K = 3
Perimeter of any polygon is defined as the sum of all sides of polygon.
Given polygon is a triangle. A triangle is any polygon which has three sides.
And as the sides of a polygon increases the perimeter also increases.
One can say that perimeter and side of a polygon has a direct relationship.
That is when we write it mathematically we write it like:
Perimeter ( P ) ∝ Sides of polygon
However given is an equilateral triangle
this means that all sides of the triangle are equal
so let us consider the side of the triangle as "s"
Thus we get that perimeter will be 3 times s
which when mathematically written will be:
Perimeter ∝ ( side)
to remove the constant of proportionality (K ) we will write
Perimeter = 3 ( side) where K = 3
