To find the area of an equilateral triangle with side length ( a = 6 ) cm, you can use the formula: [ \text{Area} = \frac{\sqrt{3}}{4} a^2 ] Substituting ( a = 6 ) cm, the area is [ \text{Area} = \frac{\sqrt{3}}{4} (6)^2 = \frac{\sqrt{3}}{4} \times 36 = 9\sqrt{3} \text{ cm}^2. ] Thus, the area of the equilateral triangle is approximately ( 15.59 ) cm².
Area = 8.06 cm2.
the formula for finding the area of a triangle is: axb/2=______ so since its an equalateril triangle, every side is 6 so you do 6x6/2 which is 18
a=1/2bh b=h=6 a=.5*6*6 a=18
Approx 525 cm.
15.588 cm2
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.
A triangle with side a: 7, side b: 7, and side c: 7 cm has an area of 21.22 square cm.

Area of equilateral triangle: 0.5*12*12*sin(60 degrees) = 187 square cm
