  • Perimeter is the total length of the boundary forming around a closed figure, going round the figure once.

  1. Perimeter of a rectangle\[\text{= 2  }\!\!\times\!\!\text{  }\left( \text{length + breadth} \right)\text{ }\!\!~\!\!\text{ }\]


Perimeter of rectangle

  1. Perimeter of a square \[\text{= 4  }\!\!\times\!\!\text{  length of its side}\]


Perimeter of square

  1. Perimeter of an equilateral triangle \[\text{= 3  }\!\!\times\!\!\text{  length of a side }\!\!~\!\!\text{  }\!\!~\!\!\text{  }\!\!~\!\!\text{  }\!\!~\!\!\text{  }\!\!~\!\!\text{ }\]


Perimeter of Equilateral triangle

  1. Perimeter of a regular pentagon  \[\text{= 5  }\!\!\times\!\!\text{  length of a sides}\]


Perimeter of Regular pentagon

  • Regular closed figures are those with the same number of sides and angles on all sides. 

  • The area of a closed figure refers to the amount of surface it covers. 

  • The following conventions are used to compute the area of a figure on squared paper:

  1. Parts of the area that are less than half a square should be ignored.

  2. If a region contains more than half a square. It should be counted as one square. 

  3. Take the size of the square in sq units if exactly half of it is counted.


Area of a Figure on Squared paper

Here to make this closed figure, we can see, there are 16 squares are unused (uncut squares outside the figure), 4 squares are half used (squares cut in halves) and 4 squares are fully used (uncut squares inside the figure).

Area $=4+\dfrac{1}{2}\times 4=6$ units

  • Area of a rectangle\[\text{= length  }\!\!\times\!\!\text{ breadth }\!\!~\!\!\text{ }\]


Area of rectangle

  • Area of a square \[\text{= side  }\!\!\times\!\!\text{  side }\!\!~\!\!\text{ }\]


Area of Square
