The dimensions given would be appropriate for an equilateral triangle.
The perimeter of the equilateral triangle is 3 times 4 = 12 cm
Perimeter of Triangle = a + b + cso if you have an equilateral with say 4 cm sides you would add4+4+4=12cmJust add up its 3 equal sides
If the sides are different lengths it ain't equilateral...
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.
This is not an equilateral triangle.
9 cm fully
24 cm
It is: 0.5*4*4*sin(60 degrees) = 7 square cm rounded to nearest integer
18.9 cm.
36 cm
P = 3(3.5 cm) = 10.5 cm
The dimensions given could be that of an equilateral triangle
