Find the perimeter that an it is provided triangle through a elevation of

.You are watching: What is the perimeter of an equilateral triangle whose height is 2√3

Explanation:

Perimeter is discovered by adding up every sides that the triangle. All sides in an equilateral triangle room equal, so we need to uncover the worth of simply one side to know the worths of all sides.

The height of an it is intended triangle divides it right into two equal 30:60:90 triangles, i beg your pardon will have actually side ratios that 1:2:√3. The elevation here is the √3 ratio, which in this case is equivalent to 8, for this reason to gain the length of the other two sides, we placed 8 over √3 (8/√3) and 2 * 8/√3 = 16/√3, i m sorry is the hypotenuse of our 30:60:90 triangle.

The perimeter is climate 3 * 16/√3, or 48/√3.
