The area of triangle ABC would be =30.4
How to calculate the area of the given triangle?
To calculate the area of the given triangle, the following steps should be taken as follows:
Given that ∆ABC is a equilateral triangle, therefore, line AB = Line BC
Using Pythagorean theorem;
Height = CB²-DB²
= 12²-6²
= 144-36 = 108
h. = √108 = 10.4
The area of the triangle;
= ½base ×height
= ½× 6 × 10.4
= 3×10.4
= 30.4
