Question

The side of a equilateral triangle
6.cm find the area, perimeter
and height of an equilateral triangle ​

Answer 1

Answer:

perimeter of equilateral triangle = sum of all sides

= 6+6+6

= 18 cm

area of a equilateral triangle = √3/4 a²

= √3/4 × 12

= 3√3 cm²

area of equilateral triangle = 1/2 × b×h

2×3√3 = 6× h

6√3 = 6×h

h = √3 cm
