The altitude of an equilateral triangle is (√3)/2*a. where 'a' is the side of the triangle. It can be just find by giving a perpendicular to the base of the triangle, the base of the triangle become a/2 and one side is a. so by applying Pythagoras theorem we will get the desired formula.
You can't as there is no hypotenuse in an equilateral triangle. The hypotenuse is the side of a triangle which is opposite a right angle (90°); all angles in an equilateral triangle are 60°.
The length of the third side of an equilateral triangle is the same as the lengths of both of the other two sides.
Equilateral triangles have all the same side lengths and scalene triangles have no similar side lengthsAn equilateral triangle has 3 equal sides whereas a scalene triangle has 3 unequal sides
An equilateral triangle has three sides of the same length. Therefore, the length of each side of an equilateral triangle with a perimeter of 63 metres is equal to 63/3 = 21 metres.
Area of Equilateral Triangle A= S2 * (Root 3)/4, where A= Area of the triangle S= Side of the triangle.
To get the area of an equilateral triangle, you just need to know the length of one side. Multiply the length of one side by the square root of three and then divide the product by four, and you will get the area of the triangle.

Add the lengths of each side together to get the perimeter.
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.
-- 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).
Well, well, well, look who's trying to flex their math muscles. If the perimeter of an equilateral triangle is 15m, that means all three sides are equal. So, divide 15m by 3 and voila, you get the length of each side - 5m. Math really can be a piece of cake, huh?
The area of an equilateral triangle with side length s is given by: A = (s^2 * sqrt(3))/4
27+27+27=81 The equation for the perimeter an equilateral triangle is "side + side + side". And since it is an equilateral all the sides are the same length.
You can't as there is no hypotenuse in an equilateral triangle. The hypotenuse is the side of a triangle which is opposite a right angle (90°); all angles in an equilateral triangle are 60°.
15.588 ft2 using the formula: (Sqrt(3)/4)×(side)²
An equilateral triangle with sides of 9 meters, silly!
