The first part of the chapter covers the following topics:
1. Perimeter of a rectangle = 2 × (length + breadth)
2. Perimeter of square = 4 × length of a side
3. Perimeter of an equilateral triangle = 3 × length of a side
Next part of the chapter emphasises on area.
The first method explained is Calculation of area by counting squares.
To calculate the area of a figure using a squared paper, the following conventions are adopted:
(a) The area of one full square is taken as 1 sq unit. If it is a centimetre square sheet, then area of one full square will be 1 sq cm.
(b) Ignore portions of the area that are less than half a square.
(c) If more than half a square is in a region. Count it as one square.
(d) If exactly half the square is counted, take its area as 1/2 sq units.
