Input Parameters Explained

Long Rectangle Side (a) – Definition and Usage

The long rectangle side, denoted as (a), represents the longest side of the original rectangle before any cuts are made. This value is essential in determining the overall dimensions of the shape and contributes to both the perimeter and area calculations. Ensuring accurate input for this value is crucial for precise measurement outcomes.

Short Rectangle Side (b) – Definition and Usage

The short rectangle side, labeled as (b), is the shorter side of the original rectangle. Along with the long side, it defines the primary shape of the rectangle before cuts are applied. This value is critical in computing the final dimensions after modifications, particularly for applications in material cutting and layout planning.

Long Cut Side (c) – What It Represents

The long cut side, marked as (c), refers to the length of the cut section that extends along the longer dimension of the rectangle. This measurement is important when cutting out sections from the material, as it affects both the remaining shape and the final calculated perimeter and area.

Short Cut Side (d) – What It Represents

The short cut side, denoted as (d), is the length of the cut along the shorter dimension of the rectangle. This value works in conjunction with the long cut side to define the removed portion of the rectangle. It plays a key role in determining how much of the material remains after the cut is made.

Slant Side (e) – Understanding the Diagonal Cut

The slant side, labeled as (e), represents a diagonal cut that may be applied instead of or in addition to straight-edge cuts. This value is especially relevant for cases where a portion of the rectangle is removed at an angle. The slant side impacts both perimeter and area calculations, requiring careful measurement to ensure precision in project planning.

Understanding the Calculations

Perimeter (p) Calculation

The perimeter of a shape is the total distance around its edges. In the case of a rectangle with a cut, the perimeter calculation changes based on the sections removed or adjusted. The formula for perimeter depends on the shape left after the cut.

For a standard rectangle, the perimeter is calculated as:

P = 2(a + b)

However, when a cut is introduced, the new perimeter must account for the additional edges formed by the cut sections. If a diagonal cut (slant side (e)) is included, the perimeter calculation incorporates this extra side:

P = a + b + (remaining edges after the cut)

Since the specific formula varies depending on the nature of the cut, this calculator automatically adjusts the perimeter calculation based on the input values.

Area (A) Calculation

The area of a rectangle is the total space enclosed within its sides. The formula for the area of an uncut rectangle is:

A = a × b

When a section is removed from the rectangle, the area of the removed section must be subtracted from the original area:

A = (Original Area) - (Removed Section Area)

If the cut includes a diagonal slant (e), the removed area may be a triangular or trapezoidal section, and the calculation adjusts accordingly. The calculator precisely determines the remaining area based on the input parameters, ensuring accurate results for planning and material usage.

How to Use the Calculator
