# NCERT Solutions Class 7 Maths Chapter 11 Perimeter and Area

The subject of geometry encompasses a detailed study of all the figures that surround us; this study majorly includes finding the area and perimeter of those figures. These parameters are important to calculate because of their usage in our everyday life. Thus, the NCERT solutions for class 7 maths chapter 11 Perimeter and Area is all about the theories of area and perimeter of different kinds of shapes such as square, rectangle, parallelogram, triangle, and circle. The understanding of units also plays a crucial role when it comes to the area and perimeter of shapes; hence the NCERT solutions class 7 maths chapter 11 Perimeter and Area also explain the conversion of lengths and areas into different units.

The concept that perimeter defines the length of the periphery of the concerned shape while area defines the space enclosed by the shape must be clear with the students so as to help with the calculations.
