NCERT Solutions for Class 7 Maths Chapter 11 Perimeter and Area
Facts
- The perimeter of a closed rectilinear figure is the total length of its boundaries.
- The area of a two-dimensional figure is the surface that it encompasses.
- A parallelogram’s area is equal to the sum of its base and height (Altitude).
-
- The area of a triangle = 1/2 x Base x Altitude for the base.
- A circle’s circumference is equal to 2πr.
- The area of a circle is equal to
πr2.?r2.

- [Equation]
- The perimeter of a regular polygon = length of each side x the number of sides.
Rectilinear Figure
A rectilinear figure is a plane figure contained by line segments that is simple if none of its sides intersect at any point other than the vertex.
Triangle
A triangle is a plane shape that is encircled by three line segments.
Quadrilateral
A quadrilateral is a plane figure with four line segments encircling it.
Parallelogram
A parallelogram is a plane figure with four line segments encircling it. In a parallelogram, the opposite sides are parallel and of equal length.
Area of a Triangle = ½ x Base x Altitude corresponding to the base.
Area of a parallelogram = base x the height.
Circumference of a Circle: It is the perimeter of a circle.
Area of a circle:
The area of the surface is the space occupied by a circle on a flat plane of length and breadth. [Equation] is the formula for calculating the area of a circle. As a result, the area of a circle is equal to one complete cycle of the circle’s radius.
Applications:
Now we’ll use the methods for calculating the areas of squares, rectangles, circles, and other shapes to calculate the sizes of various paths or borders, as well as the cost of creating them.
