This calculator determines the area of rectangles and parallelograms based on the input values for their dimensions. It is useful for students, teachers, engineers, and anyone who needs to find these areas accurately and quickly.
Formulas of Area of Rectangles and Parallelograms Calculator
Area of a Rectangle
To calculate the area (A) of a rectangle, use the formula:
A = l * w
- l is the length of the rectangle
- w is the width of the rectangle
Area of a Parallelogram
To calculate the area (A) of a parallelogram, use the formula:
A = b * h
- b is the base of the parallelogram
- h is the height of the parallelogram (the perpendicular distance from the base to the opposite side)
These formulas allow you to determine the area of both rectangles and parallelograms.
Conversion Table
Below is a table with general terms and conversions that people often search for. This will be helpful for quick reference without needing to calculate each time.
| Shape | Formula | Example Calculation |
|---|---|---|
| Rectangle | A = l * w | A = 5 * 3 = 15 |
| Parallelogram | A = b * h | A = 6 * 4 = 24 |
Example of Area of Rectangles and Parallelograms Calculator
Let’s go through an example to see how the calculator works.
- Rectangle Example
- Length (l) = 7 units
- Width (w) = 4 units
- Area (A) = l * w = 7 * 4 = 28 square units
- Parallelogram Example
- Base (b) = 5 units
- Height (h) = 3 units
- Area (A) = b * h = 5 * 3 = 15 square units
Most Common FAQs
A rectangle is a type of parallelogram with right angles. In a rectangle, opposite sides are equal, and all angles are 90 degrees. A general parallelogram has opposite sides that are equal, but the angles are not necessarily 90 degrees.
The height of a parallelogram is the perpendicular distance from the base to the opposite side. You can use a ruler or a perpendicular line to measure this distance.
This calculator is specifically designed for rectangles and parallelograms. For other shapes, you would need to use the relevant formulas or a different calculator.
