Perimeter Of A Triangle Maths Tricks And Tips Solved examples. let us consider some of the examples on the perimeter of a triangle: example 1: find the perimeter of a polygon whose sides are 5 cm, 4 cm and 2 cm. solution: let, a = 5 cm. b = 4 cm. c = 2 cm. perimeter = sum of all sides = a b c = 5 4 2 = 11. therefore, the answer is 11 cm. Perimeter of a triangle: definition, formula, examples, faqs.
Triangles Definition Formulas Types Solved Examples Faqs on calculating triangle perimeter. 1. what are the types of triangles and their perimeter formulas? there are 4 types of triangles. they are listed below with their perimeter formulas: equilateral triangle: perimeter (p) = 3 x l; right triangle: perimeter (p) = a b c; isosceles triangle: perimeter (p) = 2 x l b. Solved examples. question 1: find the perimeter of a triangle whose sides are of 6 cm, 8 cm and 12 cm. solution: question 2: find the perimeter of an equilateral triangle whose side is 6 cm. solution: being an equilateral triangle, all the sides are equal. thus, a = 6. Step 1: check if all three sides of the triangle are known. ab = 6 inches, bc = 8 inches, ac = 10 inches. step 2: use the appropriate formula and add the sides to get the perimeter. since this is a scalene triangle, we use the formula, perimeter = a b c. write the perimeter along with its units. Show step. to find the perimeter (the total distance around the triangle), add all the side lengths: 18 18 16=52 18 18 16 = 52. write the final answer with the correct units. show step. the side lengths are measured in inches, so the total perimeter is in inches. the perimeter of the sign is 52 52 inches.
