Question

the altitude of an equilateral triangle,if the length of its side as 12cm is




​

Answer 1

Step-by-step explanation:

we know that, altitude of equilateral triangle =

$\frac{ \sqrt{3} }{2} \times side$

therefore, altitude =

$\frac{ \sqrt{3} }{2} \times 12 = 6 \sqrt{3}$

Answer 2

From the given question the correct answer is:

Given:

side of equilateral triangle=12cm

To find:

the altitude of an equilateral triangle

Solution:

we have to find the altitude of an equilateral triangle

Given that,

side of equilateral triangle=12cm

we know that,

Altitude of equilateral triangle =$\frac{\sqrt{3} }{2} \times side$

Now put the value of side into the formula

Altitude of equilateral triangle =$\frac{\sqrt{3} }{2} \times 12$

                                                   =6$\sqrt{3}$cm

Hence, the Altitude of equilateral triangle is 6$\sqrt{3}$cm
