What to Focus On

  • Perimeter is boundary length.
  • Area is surface enclosed by the boundary.
  • 1 m = 100 cm.

  • Triangle perimeter = a + b + c.
  • Semi-perimeter s = (a+b+c)/2.
  • Heron's formula uses all three sides.

  • Rectangle perimeter = 2(l+b).
  • Rectangle area = l × b.
  • Rectangle diagonal = √(l²+b²).

Common Mistakes to Avoid

The height of a trapezium is one of its sloping sides.

The area of a trapezium is found by adding all four sides and multiplying by height.

Semi-perimeter s in Heron's formula is the full perimeter.
