The side of an equilateral triangle is 3.5 cm. Find its perimeter.

An equilateral triangle of side 9 cm.

The height of an equilateral triangle measures 9 cm. Find its area . (Take sqrt(3) = 1.732)

The unequal side of an isosceles triangle is 6 cm nad its perimeter is 24 cm. Find the length of other side.

One side of an equilateral triangle is 24 cm. The midpoints of its sides are joined to form another triangle whose midpoints are in turn joined to form still another triangle this process continues indefinitely. The sum of the perimeters of all the triangles is

Equation of the base of an equilateral triangle is 3x + 4y = 9 and its vertex is at point (1,2) .Find the equations of the other sides and the length of each side of the triangle .

If the area of an equilateral triangle is 16 sqrt3 cm^2 , then the perimeter of the triangle is
