How do you find the length if the perimeter and breadth is given?

In the same way, if the perimeter and the width are known, the length can be calculated using the formula: Length(L) = P/2 – w. Where P = perimeter of the rectangle; and w = width of the rectangle.

How do you find the length of the perimeter is given?

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.

How do you find the length of a rectangle with breadth and perimeter?

Explanation: To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.

What is length formula?

A = L × W A = L × W A=L×W. If you know the width, it’s easy to find the length by rearranging this equation to get.

How do you calculate area and perimeter?

To find the perimeter, add together the lengths of the sides. Start at the top and work clockwise around the shape. Area of Polygon = (Area of A) + (Area of B) To find the area, divide the polygon into two separate, simpler regions.

How do you find the perimeter of a rectangle if you know the area?

Perimeter of a Rectangle

  1. Remember the formula for perimeter and area of a rectangle. The area of a rectangle is a = length * width, while the perimeter is p = (2 * length) + (2 * width)
  2. Substitute the known values into the area formula. 36 = 4 * w.
  3. Substitute values for length and width into the perimeter formula.

What is breadth and length?

Length is commonly understood to mean the most extended dimension of a fixed object. Width or breadth usually refer to a shorter dimension when length is the longest one. Depth is used for the third dimension of a three dimensional object.

What is the formula of breadth?

Important Rectangle Formulas

Element Formula
Breadth of the rectangle P/2 – l units
Area of rectangle formula l × b sq. units
Length of the rectangle A/b units
Breadth of the rectangle A/l units

What is area length?

Length is the size of a line segment (see distance formulas), area is the size of a closed region in a plane, and volume is the size of a solid. Formulas for area and volume are based on lengths.

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.

How do you find the perimeter of a rectangle?

Example: find the perimeter of a rectangle Perimeter of a rectangle formula The formula for the perimeter of a rectangle is (width + height) x 2, as seen in the figure below: This is the equivalent of adding all four sides, since opposite sides are of equal length by definition.

What is the length and breadth of the rectangular park?

The length and breadth of a rectangular park are in the ratio 5: 2. A 2.5 m wide path running all around the outside the park has an area 305 m2. Find the dimensions of the park. Given that area of the park be 305m 2.

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.
