As you may be well aware, the RS Aggarwal Class 10 maths solutions are all connected with each other in some capacity. The topics of one can be applied to another. Similarly, Chapter 15 Perimeter and Area of Plane Figures has an association with the chapters on Triangles, Circles, and Trigonometric Identities and these skills will be useful when dealing with finding the Surface area and Volume of 3-dimensional objects.

All of these can be found at our site under the RS Aggarwal Maths Class 10 Solutions. We would suggest going through these prerequisites to develop a solid foundation before approaching this topic.

## Important formulae for RS Aggarwal Class 10 Maths Chapter 15 solutions

When attempting to solve the problems in chapter 15 you may find the following to be useful.

• Area – The amount of space occupied by the object
• Perimeter – The sum of all the lengths of the sides making the shape/object
• Semi-perimeter – Half of the perimeter of any given object.
• Square:
• Perimeter: 4a (where a is the length of the side)
• Area: a*a
• Rectangle:
• Perimeter: 2a + 2b
• Area: a*b
• Parallelogram:
• Perimeter: 2(a + b)
• Area:  b * h (where h is the height)
• Right-Angle triangle:
• Perimeter: a + b + h
• Area:  0.5 * b * h
• Isosceles triangle:
• Perimeter: 2a + b (where b is the length of the base)
• Area: 0.5 * b * h (where h is the height)
• Equilateral Triangle:
• Perimeter  = 3a (where a is the side length)
• Area = √3 / 4 * a2
