This chapter, Measuring Space: Perimeter and Area, introduces fundamental concepts of two-dimensional geometry. It begins by revisiting the perimeter and area of basic shapes like squares and rectangles. The chapter then delves into calculating the area of triangles, including the application of Heron's formula for triangles where only side lengths are known. Further, it explores methods for finding the area of various quadrilaterals such as parallelograms, rhombuses, and trapeziums, often by decomposing them into simpler triangles. The chapter also covers the area of regular polygons by dividing them into congruent triangles and concludes with the area of a circle and strategies for finding the area of composite figures by breaking them down into known geometric shapes.
