## What is a formula of perimeter of rectangle?

What is the formula for the perimeter of a rectangle? The formula for the perimeter of a rectangle is, P = length + breadth + length + breadth. Or, P = 2(length + breadth)

## How do you calculate a perimeter?

To find the perimeter of a rectangle, add the lengths of the rectangle’s four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.

### What is the perimeter and area of rectangle?

The perimeter P of a rectangle is given by the formula, P=2l+2w , where l is the length and w is the width of the rectangle. The area A of a rectangle is given by the formula, A=lw , where l is the length and w is the width.

### What is the formula of rectangular?

A rectangle is a type of quadrilateral, a 2d shape that has four sides and four vertices. All the four angles of the rectangle are right angles or equal to 90 degrees….Area of Rectangle Formula.

The formula for the Area of a Rectangle
Area of a Rectangle A = l × b

What is the formula to find the perimeter of a rectangle?

To find the perimeter of rectangle we add the lengths of its sides. Thus, the perimeter of a rectangle with the length of a a and the width of b b is P = a + b + a + b = 2 × a + 2 × b = 2 × (a + b) P = a + b + a + b = 2 × a + 2 × b = 2 × (a + b)

What are the rules supported by the perimeter calculator?

Our perimeter calculator also supports the following rules: SAS (side, angle, side), SSA (side, side, angle), ASA (angle, side, angle) and the hypothenuse and side rule for right-angled triangles.

## How do you calculate the area of a rectangular shape?

Also a graphic will be shown of a scaled drawing to the correct proportions and labelled with each dimension and calculated area. Formula. The formula used by this calculator to calculate the area of a rectangular shape is: A = L · W. Symbols. A= Area; L = Length; W = Width; Area Dimensions – Length & Width

## What are the units of area and perimeter?

The perimeter is measured in units such as centimeters, meters, kilometers, inches, feet, yards, and miles. The area is measured in units units such as square centimeters (cm2) ( c m 2), square meters (m2) ( m 2), square kilometers (km2) ( k m 2) etc.
