Question

If the area of an equilateral triangle is 64sqrt(3) cm², then the side of the triangle is​

Answer 1

Step-by-step explanation:

1 Since area = √3/4a²

2. √3/4a²=64√3cm²

3. a²=64×4cm²

4. a²=256cm²

5. a=16cm²

since sides of equilateral triangle is equal

hence Side(a)=16cm is the correct answer.
