Area of Irregular Shapes
Real shapes (leaves, lakes, countries) are irregular. Method: trace on grid paper. Count squares (use half-square rule). Area of India โ 3.3 million kmยฒ. Architects use this to find area of awkward rooms. Farmers use this to measure field areas. Computer programs can calculate area of any shape by similar counting of pixels (tiny squares).
