side plus side plus side...or maybe u need touse the pythgorean theorem... a squared+b squared= c squared
c= hypotenuse
a and b= the legs
:D
There is no reason for the perimeter of a triangle to have any relation to the perimeter of an unrelated rectangle!
The perimeter of a triangle 4.5 by 1.5 is: 10.74
You find the perimeter of a triangle by adding all the sides. There is no special rule for finding the perimeter.
The minimum perimeter is when the triangle is an equilateral triangle. The perimeter of any other triangle with the same area will be longer. In the case of an equilateral triangle area = (√3)/4 × side² → side = √(4×6.5 cm²/√3) → perimeter = 3 × side = 3 × √(4×6.5 cm²/√3) ≈ 11.62 cm → The triangle has a perimeter greater than or equal to approx 11.62 cm.
If you know the perimeter, there is no need to find it again.
