Find the area of an equilateral triangle if its perimeter is 18 ft
The triangle's altitude is 8.7 (8.66025) cm.
Find the area of an equilateral triangle that has a perimeter of 21 inches. Round the answer to one decimal place.
Perimeter of Triangle = a + b + cso if you have an equilateral with say 4 cm sides you would add4+4+4=12cmJust add up its 3 equal sides
An equilateral triangle has three sides of exactly the same length. Therefore, if one side of the triangle is equal to 12 yards, then the perimeter of the triangle is equal to 12 x 3 = 36 yards.
An equilateral triangle has 3 equal interior angles each of 60 degrees. There are two right angled triangles in an equilateral triangle. So we can use trigonometry to find the length of one side of the equilateral triangle then multiply this by 3 to find its perimeter. Hypotenuse (which is one side of the equilateral) = 15/sin 60 degrees = 17.32050808 17.32050808 x 3 = 51.96152423 Perimeter = 51.96152423 units.
Find the area of an equilateral triangle if its perimeter is 18 ft
If the triangle is equilateral, you simply divide the perimeter by three to find the length of each side. If the triangle is not equilateral, you will need more information to determine the length of each side.
The triangle's altitude is 8.7 (8.66025) cm.
Find the area of an equilateral triangle that has a perimeter of 21 inches. Round the answer to one decimal place.
If the triangle is equilateral, you don't have a problem, but if not you have to measure the sides.
Altitude = 10.4 (10.3923) cm
That depends on what type of triangle is if the side given is equal to the perimeter divided by 3 then it is an equilateral triangle.
Here are a couple Find the altitude of a triangle with base 3 and hypotenuse 5. Find the altitude of an equilateral triangle with each side to 2
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.
