Question

If each side of the equilateral triangle is 22 cm, then what is the area of that triangle

Answer 1

Answer:

area of an equilateral triangle = $\sqrt{3}$÷ 4× a² (where,a is the side)

                                                   = $\sqrt{3}$÷ 4× 22²

                                                    = $\sqrt{3}$÷ 4× 484

                                                  = 209.58 cm²
