Perimeter and Area

Perimeter is the distance around a closed figure whereas area is the part of plane
occupied by the closed figure.
Area is the measure of the part of plane or region enclosed by it.
We have learnt how to find perimeter and area of a square and rectangle in the
earlier class. They are:
(a) Perimeter of a square = 4 × side
(b) Perimeter of a rectangle = 2 × (length + breadth)
(c) Area of a square = side × side
(d) Area of a rectangle = length × breadth
Area of a parallelogram = base × height
Area of a triangle = (area of the parallelogram generated from it)

Area of equilateral triangle =

The distance around a circular region is known as its circumference.

Area of a circle , where r is the radius of the circle.
