One vertex of an equilateral triangle is `(2,2)` and its centroid is `(-2/sqrt3,2/sqrt3)` then length of its side is

One vertex of an equilateral triangle is (2,2) and its centroid is (-(2)/(sqrt(3)),(2)/(sqrt(3))) then length of its side is

The vertex of an equilateral triangle is (2,-1) and the equation of its base is x+2y=1. The length of its sides is

The area of an equilateral triangle is 81sqrt(3)cm^2 . Its height is

The equation of the base of an equilateral triangle is x+y=2 and its vertex is (2,-1). Find the length and equations of its sides.

One side of an equilateral triangle is 3x+4y=7 and its vertex is (1,2). Then the length of the side of the triangle is

One side of an equilateral triangle is 3x+4y=7 and its vertex is (1,2). Then the length of the side of the triangle is

If the equation of base of an equilateral triangle is 2x-y=1 and the vertex is (-1,2), then the length of the sides of the triangle is sqrt((20)/(3)) (b) (2)/(sqrt(15))sqrt((8)/(15)) (d) sqrt((15)/(2))
