The Perimeter of a triangle whose sides are 15cm, 9cm, and 12cm is 36cm.
Given,
Length of side1 = 15cm
Length of side2 = 9cm
Length of side3 = 12cm
To Find,
The perimeter of a triangle.
Solution,
Before solving the question, let's understand the concept of a triangle.
Triangle:-Polygons with three sides and three angles are known as triangles. A triangle is a geometrical shape consisting of three vertices that are connected by a line. The symbol denotes it as'△.'
The perimeter of a Triangle:- Each polygon's perimeter is determined by the length of its sides.
Perimeter = side1 + side2 + side3.
So, let's put the value of sides in the above formula to find the perimeter.
Length of side1 = 15cm
Length of side2 = 9cm
Length of side3 = 12cm
Perimeter = side1 + side2 + side3.
= 15 + 9 + 12
= 36 cm.
The Perimeter of a triangle whose sides are 15cm, 9cm, and 12cm is 36cm.
