What is the formula for polygon?
Polygon Formula The important polygon formulas are: The sum of interior angles of a polygon with “n” sides =180°(n-2) Number of diagonals of a “n-sided” polygon = [n(n-3)]/2. The measure of interior angles of a regular n-sided polygon = [(n-2)180°]/n.
What shapes formula is Bxh?
Area of a Rectangle formula equals b x h (base x height )
What is the formula of triangle rectangle and square?

What is Square formula?
The area of a square is calculated with the help of the formula: Area = s × s, where, ‘s’ is one side of the square. Since the area of a square is a two-dimensional quantity, it is always expressed in square units.
What is a 1/2 XBXH?
To find the area of a triangle, multiply half of the triangle’s base times its height. Mathematically, this procedure is described by the formula A = 1/2 x b x h, where A represents the area, b represents the base and h represents height.
What is the formula for volume of a 3d shape?
Answer: The correct answer is V=13πr2h. The general formula for the volume of a cone or pyramid is V=13Bh, where B is the area of the base.
What is perimeter of 2D shapes?
The perimeter is the total distance around the edge of a 2D shape. Examples of units of distance are millimetres (mm), centimetres (cm) and metres (m).
What’s the formula of square?
Perimeter, Area, and Volume
| Table 2. Area Formulas | ||
|---|---|---|
| Shape | Formula | Variables |
| Square | A=s2 | s is the length of the side of the square. |
| Rectangle | A=LW | L and W are the lengths of the rectangle’s sides (length and width). |
| Triangle | A=12bh | b and h are the base and height |
What formula is a 1/2 b1 b2 H?
The area of a trapezoid is A= (1/2) h (b1 + b2) , where h=height of the trapezoid, b1= 1st base, and b2= second base.
What is the formula to find the area of a shape?
FORMULAS FOR SHAPES. Area of semicircle = Πr 2 / 2. Area of quadrant = Πr 2 / 4. Area of rhombus = (d 1 x d 2) / 2. When we know the radius “r” of the circle and central angle “θ” of the sector : When we know the radius “r” of the circle and arc length “l”:
What are the geometry formulas in maths?
The main concern of every student about maths subject is the Geometry Formulas. They are used to calculate the length, perimeter, area and volume of various geometric shapes and figures. There are many geometric formulas, which are related to height, width, length, radius, perimeter, area, surface area or volume and much more.
How do you calculate compound interest on the GMAT?
All interest formulas use the following variables: P = starting principle; r = annual interest rate; t = number of years. Compound Interest = P (1 + r/x)^ (xt); x = number of times the interest compounds over the year Download our GMAT formula sheet to help you study your GMAT formulas.
