The perimeter of the equilateral triangle will be 76.2 in
Explanation:
Altitude of an equilateral triangle, H = 22 in
Perimeter, p = ?
Let a be the side of the triangle
We know:
[tex]H = \frac{a\sqrt{3} }{2} \\\\22 = \frac{a\sqrt{3} }{2} \\\\a = 25.4 in[/tex]
Perimeter = 3a
P = 3 X 25.4 in
P = 76.2 in
