Chapter 10 : Perimeter and Area

What will you learn in this chapter

In this chapter, we will be learning about perimeter and area. Perimeter is the distance around a shape, and we will learn how to find the perimeter of different shapes when we know the side lengths or need to measure them. We will also learn how to estimate the perimeter and compare it with the actual measured value.

Next, we will learn about the area of triangles, parallelograms, kites, and trapeziums. We will use different methods to estimate the area of these shapes and derive the formulas based on the area of rectangles.

Lastly, we will explore the relationship between perimeter and area. We will make and verify conjectures about this relationship and solve problems involving the perimeter and area of various shapes like triangles, rectangles, squares, parallelograms, kites, trapeziums, and combinations of these shapes.
