You have studied about figures of different shapes such as squares,rectangles, triangles and quadrilaterals. You have also calculated perimeters and geometry help free the areas of some of these figures like rectangle, square etc. For instance, you can find the area and the perimeter of the floor of your classroom.
Let us take geometry problems free around the floor along its sides once; the distance we walk is its
perimeter. The size of the floor of the room is its area.
So, if your classroom is rectangular with length 10 m and width 8 m, its perimeter would be 2(10 m + 8 m) = 36 m and its area would be 10 m × 8 m, i.e., 80 m2. Unit of measurement for length or breadth is taken as meter (m) or centimeter (cm) etc. Unit of measurement for area of any plane figure is taken as square metre (m2) or square centimeter (cm2) etc.
Suppose geometry answers free that you are sitting in a triangular garden. How would you find its area?
Area of a triangle =1/2× base × height
