Add the lengths of each side together to get the perimeter.
15.2 inches.
12
It is: 0.5*base*perpendicular height
-- 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
Area = 0.5*base*height Alternatively area = 0.5*side squared*sin(60 degrees)
