- The amount of surface enclosed by a closed figure is called its area.
- Surface Area of a figure can be broken into exact numbers or approximate numbers of square units
- Depending upon the figure, some of square units may be completely covered, or partially covered.
- While using a squared paper, to calculate the area of a figure , we may use the conventions :

- Perimeter is the distance covered once along the boundary of a closed figure .
- Perimeter of a rectangle = 2 × (length + breadth)
- Perimeter of a square = 4 × length of a side
- Perimeter of an equilateral triangle = 3 × length of a side
