### What is the perimeter of a triangle that has a area of 6.5 cm?

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.
