Calculating Perimeter of Triangle
Calculating Perimeter of Triangle
Perimeter of Triangle: The total distance around the outside or boundary of a triangle.
Perimeter of any figure: Like any polygon, the perimeter is the total distance around the outside, which can be found by adding together the length of each side.
Or as a formula: Perimeter = a + b + c
where a,b and c are the lengths of each side of the triangle.
We will discuss here how to find the perimeter of a triangle. We know perimeter of a triangle is the total length (distance) of the boundary of a triangle.
The perimeter of a triangle ABC
= AB + BC + CA
= 2 cm + 4 cm + 3 cm = 9 cm (add the length of each side of the triangle)
Perimeter of the triangle = Sum of the sides.
Illustration: If 2 sides of the triangle are 3cm, 7cm and perimeter is 55cm then what will be the length of the third side?
Solution: Let third side of triangle = x
As we know that Perimeter of triangle = Sum of its all sides
Hence, 55 = 3 + 7 + x
55 = 10 + x
55 - 10 = x
x = 45 cm
Hence, third side of the triangle = 45cm
Calculate the perimeter of a triangle if its sides are 3 dm, 41 dm, and 1589 dm respectively. | |||
