Various shapes have various formulas to calculate the area, known as area formulas . Area formulas are essential tools used in mathematics to calculate the amount of space enclosed by different two-dimensional shapes. Learn how to find the area of different shapes using formulas for squares, rectangles, circles, triangles, parallelograms, rhombi, trapezoids, ellipses and more. See examples, definitions and diagrams of each shape. The formulas to find the areas of a few shapes are given below: Area of circle = πr^2, where r is the radius of the circle. Area of triangle = (1/2)bh, where b is the base and h is the triangle’s height. Area of square = a^2, where a is the side of a square. Area of rectangle = lb, where l is the length and b is the rectangle’s breadth. Area and Perimeter Formula are the two major formulas for any given two-dimensional shape in Mathematics. In geometry, you will come across many shapes such as circle, triangle, square, pentagon, octagon, etc. In real life as well, you will come across different types of objects having different shapes and sizes, which occupy some space in a place and their outline distance specifies the total length of the object.
