Solved Examples on Perimeter
Example 1: Find the Perimeter of a Square with a side length of 5 meters.
Solution:
Given,
- Side of Square(a) = 5 m
Perimeter of Square(P) = 4a
P = 4(5)
P = 20 m
Thus, the perimeter of the square is 20 m.
Example 2: Find the Perimeter of a Rectangle with a length of 10 meters and a width of 5 meters.
Solution:
Given,
- Length of Rectangle(l) = 10 m
- Breadth of Rectangle(b) = 5 m
Perimeter of Rectangle(P) = 2(l+b)
P = 2(10+5)
P = 30 m
Thus, the perimeter of the rectangle is 30 m.
Example 3: Find the Perimeter of a Triangle with side lengths 3 meters, 4 meters, and 5 meters.
Solution:
Given,
- First Side (a) = 3 m
- Second Side (b) = 4 m
- Third Side (c) = 5 m
Perimeter of Triangle (P) = a + b + c
P = 3 + 4 + 5
P = 12 m
Thus, the perimeter of the triangle is 12 m
Example 4: Find the Perimeter(Circumference) of a circle with a radius of 7 meters.
Solution:
Given,
- Radius of Circle(r) = 7 m
Circumference of Circle(C) = 2πr
C = 2×22/7×7
C = 44 m
Thus, the circumference of the circle is 44 m.
Example 5: Find the perimeter of a Trapezium with bases 6 meters and 8 meters, and height 4 meters.
Solution:
Given,
- Base of Trapezoid, b1 = 6 m and b2 = 8 m
- Height of Trapezoid(h) = 4 m
Perimeter of Trapezium(P) = (b1 + b1) + 2h
P = (6+8) + 2(4)
P = 22 m
The Perimeter of the Trapezum is 22 m.
Perimeter
Perimeter is defined as the sum of all the sides of any polygon. The perimeter of any figure is the sum of the length of all the boundaries of that figure. Perimeter of any figure gives us the length of all the boundaries we can understand this by the following example, suppose we have to find the length of wire required to fence a square then the perimeter of the square field gives the required result as it gives the length of the boundary of the square field.
In this article we will learn about Perimeter, how to calculate the perimeter, various formulas used to calculate the perimeter, examples of the perimeters, and others in detail.
