## Area Tricks and Formulas

Hello Friends, We are sharing with you Area Tricks and Formulas. This is very helpful various mathematical problems to be solved.

1. Rectangle: The area of a rectangle is the product of its length and width. A = lw
2. Square: The area of a square is the square of its side length. A = s^2
3. Triangle: The area of a triangle is half the product of its base and height. A = 1/2bh
4. Parallelogram: The area of a parallelogram is the product of its base and height. A = bh
5. Trapezoid: The area of a trapezoid is half the product of the sum of its bases and its height. A = 1/2(a + b)h
6. Circle: The area of a circle is the product of pi and the square of its radius. A = πr^2
7. Sector of a Circle: The area of a sector of a circle is the product of the angle measure of the sector (in radians) and the square of the radius, divided by 2. A = θr^2/2, where θ is in radians.
8. Rhombus: The area of a rhombus is half the product of its diagonals. A = (d1*d2)/2, where d1 and d2 are the diagonals.
9. Regular Polygon: The area of a regular polygon with n sides and side length s is (ns^2)/(4tan(π/n)).
10. Heron's Formula: For a triangle with sides of lengths a, b, and c, and semiperimeter s=(a+b+c)/2, the area is given by A = sqrt(s(s-a)(s-b)(s-c)).
11. Ellipse: The area of an ellipse is the product of pi and the lengths of its semi-major and semi-minor axes. A = πab, where a and b are the lengths of the semi-major and semi-minor axes respectively.
12. Regular Tetrahedron: The area of a regular tetrahedron with side length s is (sqrt(3)*s^2)/4.
13. Regular Hexagon: The area of a regular hexagon with side length s is (3*sqrt(3)*s^2)/2.
14. Kite: The area of a kite is half the product of its diagonals. A = (d1*d2)/2, where d1 and d2 are the lengths of the diagonals.
15. Sector of an Ellipse: The area of a sector of an ellipse with semi-major and semi-minor axes a and b, and central angle θ (in radians), is (1/2)abθ.

Remember to always label the units of your measurements to make sure you are using the correct units in your calculations.
