Rectangle Area Calculator
A rectangle is a flat geometric shape formed by four sides and four right angles. The opposite sides of a rectangle are parallel and congruent, meaning they have the same length. The area of the rectangle is the measure of the surface bounded by its sides. The area of the rectangle is one of the simplest and most frequent in geometry.
To calculate the area of a rectangle, there is a unique and easy formula that depends on the available data. The formula uses the base and height of the rectangle, which are the sides adjacent to the right angle. This formula is:
A = b·h
Where A is the area of the rectangle, b is the base of the rectangle, and h is the height of the rectangle. This formula can be used when the value of the base and height is known or when they can be obtained from other data.
In addition to the area, another important magnitude is the perimeter of the rectangle, which is the measure of the rectangle's outline. The perimeter of the rectangle is equal to the sum of its four sides. Since the opposite sides are equal, the perimeter can be calculated using the following formula:
P = 2·(b + h)
Where P is the perimeter of the rectangle, b is the base of the rectangle, and h is the height of the rectangle. This formula can be used when the value of the base and height is known or when they can be obtained from other data.
To simplify the calculation of the rectangle's area and perimeter, there are online calculators that allow you to enter the available data and get the result automatically. Some calculators also show the steps of the solution and the stages of the formula used.
How to calculate the area of a rectangle?
To calculate the area of a rectangle, simply multiply the base by the height. The formula is:
A = b·h
Where A is the area of the rectangle, b is the base of the rectangle, and h is the height of the rectangle.
How to calculate the perimeter of a rectangle?
To calculate the perimeter of a rectangle, simply add its four sides. Since the opposite sides are equal, you can use the following formula:
P = 2·(b + h)
Where P is the perimeter of the rectangle, b is the base of the rectangle, and h is the height of the rectangle.
What are the base and height of a rectangle?
The base and height of a rectangle are the sides adjacent to the right angle. The base is the horizontal side and the height is the vertical side. The base and height can have any positive value, as long as they are different from zero.
