Add the lengths of each side together to get the perimeter.
15.2 inches.

It is: 0.5*base*perpendicular height
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.
-- 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).
Base times height and divided by 2.
The area of an equilateral triangle with side length s is given by: A = (s^2 * sqrt(3))/4
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.
Turn the triangle into a square work out the area for that then half your answer ---- For an equilateral triangle, use the formula 1/2 x base x perpendicular height to work out the area.
The answer is 32 cm. because the formula for the area of a triangle is 1/2*base*height. Since its an equilateral triangle, it has equal sides. so just substitute it to the given formula. It will be 1/2*8*8 so therefore its 32 :)
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.
Perimeter of equilateral triangle: 24 units Area of equilateral triangle: 27.713 square units rounded to three decimal places
A triangle has area, not volume.
The altitude formula is like this: Area x 2 divided by the base ( Ax2:b) The area formula is base x height divided by 2
