Area Formulas

Area is the size of a two-dimensional surface.  It is defined as the amount of two-dimensional space occupied by an object. Area formulas have many practical applications in building, farming, architecture, science. The area of a shape can be determined by placing the shape over a grid and counting the number of squares that covers the entire space.For example area of square can be calculated using $a^{2}$ where, a is the length of it’s side.

Area = l $\times$ w l =  length

w  = width

Area of Square Area  = $a^{2}$ a = sides of square
Area of a Triangle Area = $\frac{1}{2}$bh b = base
h = height
Area of a Circle Area = $\pi$$r^{2}$ r= radius of circle
Area of a Trapezoid Area =$\frac{1}{2}$(a + b)h a =base 1
b = base 2
h = vertical height
Area of Ellipse Area = $\pi$ab a = radius of major axis
b = area of minor axis
