![]() ![]() Let a triangle be given with sides a = 4 cm, b = 6 cm, c = 7 cm. The formula for the perimeter of a triangle looks like this:Īn example of calculating the perimeter of a triangle. ![]() Quite often, this value helps to find the area or is used to calculate other parameters of the figure. P = A + B + C.The perimeter of a triangle, as in other things and any figure, is called the sum of the lengths of all sides. The perimeter of a triangle can be calculated by adding the lengths of all the three sides of the triangle. The formula for calculating the area of a triangle is: A = 1/2 (b × h). What is the formula of area and perimeter of Triangle? For instance, if a triangle has sides a, b, and c, then its perimeter is P = a + b + c. How to Calculate the Perimeter of a Triangle?Īdd the lengths of the triangle’s sides to find its perimeter. ![]() In other terms, the perimeter of a triangle is the length of its boundary. The total distance around a triangle’s edges is known as its perimeter. What does the Perimeter of a Triangle Mean? Bleaching Powder Formula And Chemical Name.Unit Of Force- What Is The SI & CGS Unit Of Force?.So, the perimeter of the triangle = 6 + 8 + 10 = 24 cm. Therefore, Perimeter of the given triangle is 45 cm.Įxample 3: What is the length of the third side of a triangle whose perimeter is 50 cm and two sides are 15 cm and 12 cm?Įxample 4: Calculate the Perimeter of a Right Triangle with Base as 6 cm and height as 8 cm.įirst, using the Pythagorean Theorem, we can calculate the hypotenuse of the right triangle. Solution: Because all the three sides are equal in length, the triangle given is an equilateral triangle, and hence the perimeter can be calculated by the formula: P = 3 × L. Perimeter = Sum of all sides = A + B + C = 7 + 8 + 5 = 20Įxample 2: Find the perimeter of a triangle which has each side is 15 cm. Solution: Because, all three sides are unequal, therefore it is a scalene triangle, and we can only calculate the perimeter by the conventional method. Where A, B, C are the lengths of the sides of a triangle.Įxample 1: Find the perimeter of a triangle whose sides are 7 cm, 8 cm and 5 cm. Where L is the length of the sides of triangle.īecause the sides of a scalene triangle are all of different lengths, therefore it can only be calculated by the conventional formula: Perimeter, P= A + B + C Where A is the length of two equal sides and B is the length of the third side.īecause all the sides of a equilateral triangle are equal to each other, therefore the perimeter of a equilateral triangle can also be calculated by the formula: Perimeter, P= 3 × L Perimeter of Isosceles Triangleīecause two sides of an Isosceles triangle are equal and one side is of different length than the other two, therefore the perimeter of an isosceles triangle can also be calculated by the formula: Perimeter, P= (2 × A) + B But there are different methods as well to calculate to perimeter of different types of triangles. The perimeter of a triangle can be calculated by adding the lengths of the three sides of triangle. ![]() If a triangle has three sides, a, b, and c, then, Perimeter, P = a + b +cīuy Online NEET 2022 Revision Course Perimeter of Different Kinds of Triangle As a result, the perimeter of a triangle is equal to the total of its three sides. In most cases, the perimeter of a closed shape figure is equal to the length of the figure’s outer line. Join Rapid Revision Course For JEE Main/Advanced 2022 Course Perimeter of Triangle- Formula
