    @Foreverisabell Triangle Formula : Area of Triangle = l * b/2 Perimeter of Triangle = a + b + c Area of Equilateral Triangle = (Sqrt(3) / 4) * l² Area of SAS Triangle = ½ * l * b * SinC where l = length, b = breadth a, b, c = sides of triangle

    @some_someone so you would do square root 3 divided by 4 times 12 squared?

    The length of a equalateral triangle is\[ (x/2)\sqrt{3}\] where x is the length of one side

    Find the area of a equilateral triangle from the given length 3. Find the area. Area = (Sqrt(3) / 4) * l² = (1.73 / 4) * 12² = 0.4325 * 144 = 62.28 so ~ 62.354

    (14.1*9)/(2*12)=5.2 which must round up to 6.
