Area of Equilateral Triangle A= S2 * (Root 3)/4, where A= Area of the triangle S= Side of the triangle.

### An equilateral triangle and a square have equal perimeters what is the ratio of the area of the triangle to the area of the square?

If an equilateral triangle and a square have equal perimeters, then the ratio of the area of the triangle to the area of the square is 1:3.

### What is the area of an equilateral?

Area of an equilateral triangle is s*(sqrt 3)/2, where s is the length of a side, or: area = s * 0.866666. . .

### What is the area of an equilateral triangle of side 2a?

The height of an equilateral triangle is &radic;3/2 x side_length. So for an equilateral triangle of side length 2a, the area is: area = 1/2 x base x height 1/2 x (2a) x (&radic;3/2 x 2a) = &radic;3 a2

### An equilateral triangle has an area of What is the length of one side?

You might want to give an area, it's impossible to answer your question as it is. The area of an equilateral triangle is [side2]*sqrt(3)/4, so reaarange: Side = 2*sqrt(area/sqrt(3))

### What is the area of an equilateral triangle if the coordinate points -2 9 and -7 -3 are the same distance apart as the height of the equilateral triangle?

If: (-2, 9) and (-7, -3) is the same distance then the height of the triangle is 13 units and each length of the equilateral triangle is 15.011107 units. Area = 0.5*13*15.011107 = 97.572 square units to 3 decimal places

### What is the formula for the area for an equilateral triangle?

-- The area of any triangle is 1/2 (length of the base x height). -- For an equilateral triangle, that's equivalent to 1/2 x sqrt(3) x (length of a side).

### What is the formulae fo equalertal triangle?

The formula for the perimeter of an equilateral triangle is P = 3s, where P is the perimeter and s is the length of one side. The formula for the area of an equilateral triangle is A = (s^2 * sqrt(3)) / 4, where A is the area and s is the length of one side.

### What would be the area for an equilateral triangle?

60 because there are 3 sides in a triangle and 60 x 3 =180, triangles are always equal to 180 * * * * * The above "answer" has nothing to do with the question! The area of an equilateral triangle with sides of s cm is s*sqrt(3)/4 square cm.

### What is the perimeter of a triangle that has a area of 6.5 cm?

The minimum perimeter is when the triangle is an equilateral triangle. The perimeter of any other triangle with the same area will be longer. In the case of an equilateral triangle area = (&radic;3)/4 &times; side&sup2; &rarr; side = &radic;(4&times;6.5 cm&sup2;/&radic;3) &rarr; perimeter = 3 &times; side = 3 &times; &radic;(4&times;6.5 cm&sup2;/&radic;3) &asymp; 11.62 cm &rarr; The triangle has a perimeter greater than or equal to approx 11.62 cm.
