Question

The perimeter of an equilateral traingle is 6. The length of the altitude of the traingle is _______ . Please answer quickly it's important.

Answer 1

The side of the equilateral triangle becomes 2.
So the altitude will become root 3.

Answer 2

Perimeter = 6...here x is the side of the triangle

3x= 6
X= 2cm

Area of equilateral triangle is
√3/4 × a × a = √3 × 2 × 2 / 4 = √3 cm sq

Also area of triangle is

1/2 × base × height = √3

1/2 × 2 × height = √3

Hence height or altitude = √3
