NCERT Solutions for Class 7 Mathematics Chapter 11: Perimeter and Area

Content Curator

NCERT Solutions for Class 7 Mathematics Chapter 11 Perimeter and Area is provided in this article. Two-dimensional forms have two key properties: area and perimeter. The perimeter of a form is defined by the distance between its boundary and the area occupied by it. Some of the important topics in Perimeter and Area chapter includes:

Rectangle
Difference Between Area and Perimeter
Area of Square Using Diagonal
Perimeter and Area Formula
Perimeter of Triangle
Square Footage Formula

NCERT Solutions for Class 7 Mathematics

Area: It is the two-dimensional space occupied within the boundaries of a geometrical figure.

Perimeter: It is the length of the boundary of a two-dimensional geometrical figure.

Example 1: Find the area of a square of side 5 cm.

Ans. We know that,

Area of square = a x a

Area = 5 x 5

Area of square = 25 sq.cm

Example 2: Find the perimeter of square of side 10 cm.

Ans. We know that,

Perimeter of square = 4a

Perimeter = 4 x 5

Perimeter = 20 sq.cm
