AREA

Area is the amount of space inside the boundary of a plane figure.

Areas Of 4 Common Shapes

1)Square

Area = a²(Where a is the side)

2)Rectangle

Area = l × b (Where l is the length and b is the breadth )

3)Circle

Area = πr² (Where r is the radius of the circle )

4)Triangle

$\sf Area = \dfrac{1}{2} bh (Where \: b \: is \: the \: base \: and \: h \:is \: the \:height \:of \: the \: triangle)$

PERIMETER

Perimeter is the region along the the boundary of a plane figure.

Perimeter Of 4 Common Shapes

1)Square

Perimeter = 4a (Where a is the side)

2)Rectangle

Perimeter = 2(l+b) (Where  l is the length and b is the breadth )

3)Circle

Perimeter = 2πr (Where r is the radius of the circle )

4)Triangle

Perimeter = a+b+c (Where a , b and c are sides of a triangle )

Radius

Radius is the line segment that is drawn from a point on the perimeter of a circle to the center of the circle.
