Question

1. The height of an equilateral triangle is 6 cm, then the area of the triangle is
(a) 15√3 (b) 3√3 (c) 12√13 (d) none of these​

Answer 1

Answer: c option is correct

Step-by-step explanation:

Altitude = Height = 6 cm

Let length of side be 'a'

So , √3/2 a = 6

So a = 12/√3

So a = 4√3 cm

This 'a' is the length of the side

Now, area = (√3/4) × a²

So, Area = (√3/4) × (4√3)²

So, Area = (√3/4) × (16×3)

So, Area = ✓3 × 4 × 3

So, Area = 12√3cm²
