Question

If the perimeter of a equilateral triangle is 36 cm calculate area and height

Answer 1

hii dear here is your answer

Given perimeter of equilateral triangle = 36 cm
Let the side of equilateral triangle be 'a' cm
Hence 3a = 36
Therefore, a = 12 cm
Area of equilateral triangle = (√3/4) x a2 sq units
                                      = (√3/4) x 122
                                      = (√3/4) x 144 = 36√3 sq
                                      = 62.3 sq cm
