Simple Closed Curve
A curve or a figure having the same beginning and ending point is called a closed curve. For examples, a triangle, a square, or any close curved shape.

Perimeter of a Figure
The Greek word “peri” means ‘around’ and “meter” means ‘measure’. So, perimeter means measuring around a figure or a curve.
The distance around a figure or the length of the boundary of a figure, is called the perimeter of the figure.
Example:
A rectangular shape, if we start from A, move along AB, then BC, then CD and then DA, we reach back at the starting point A. Only in the case of a simple closed figure, it is possible.
The perimeter of this figure is AB + BC + CD + DA
= 7 cm + 4 cm + 5 cm + 3 cm = 19 cm.
Perimeter of a Rectangle
A rectangle which sides are of length 8 cm and breadth 6 cm. If we go round it once, the distance covered will be 8 cm + 6 cm + 8 cm + 6 cm = 28 cm.
Sum of the four sides of a rectangle is called the perimeter of the rectangle.
If we denote the length and breadth of the rectangle by l and b respectively,
Then Perimeter of the rectangle = l + b + l + b = 2l + 2b = 2 (l + b).
The perimeter P of a rectangle whose length and breadth are l and b respectively is given by P = 2 (l + b).
Perimeter = 2 (length + breadth)
Note: The unit of the perimeter is the same as that of the length and the breadth.
Class 6 Maths Exercise 10.1 Important Questions
A rectangular field is 45 m long and 32 m wide. Find its perimeter.
Length of the field = 45 m Breadth of the field = 32 m
So, Perimeter of the field = 2 (length + breadth)
= 2 (45 + 32) m = 2 × 77 m = 154 m.
How to find the perimeter of a rectangle?
To get the perimeter of a rectangle, add all the sides of it. There are 4 sides of a rectangle whose sum will give its perimeter.
What is the formula for the perimeter of a rectangle?
The formula for the perimeter of a rectangle is, P = length + breadth + length + breadth.
Or, P = 2(length + breadth)
What is the formula for area of rectangle?
The formula for area of rectangle is:
Area = Length x Breadth
If the perimeter P of a rectangle and one of length (l) or breadth (b) are known, we can find the other as follows:
Length = ½ Perimeter – Breadth
and Breadth = ½ Perimeter – Length
What are the concepts of perimeter in exercise 10.1 of 6th standard Maths?
In exercise 10.1 of 6th standard Maths, Perimeter is the distance covered along the boundary forming a closed figure when you go round the figure once.
What are some real-life situations of perimeter in Exercise 10.1 class 6th Maths?
The idea of the perimeter is widely used in our daily life.
1. A farmer who wants to fence his field.
2. An engineer who plans to build a compound wall on all sides of a house.
3. A person preparing a track to conduct sports.
All these people use the idea of ‘perimeter’.
How many examples are there in exercise 10.1 of Maths grade 6th?
Nine examples are there in exercise 10.1 of Maths grade 6th. In all the examples, students have to find out the perimeter of the given shape. Examples 4 and 7 of exercise 10.1 are important from the exam point of view.
Which questions of exercise 10.1 of class 6th Maths are significant for exams?
Exercise 10.1 of class 6th Maths has 17 questions. All questions of this exercise are good, logical, and important. But, questions 1, 3, 11, 14, 15, and 16 of this exercise are most important from the exam point of view. Teachers can give these questions in the exams.
