Rectangle Area Calculator

Results

Area is a geometrical term defined as the space occupied by an object in a two dimensional surface. Rectangle area is the most commonly used. To buy a carpet for room, we'll have to estimate the area covered by the rectangular floor. Rectangle area calculator will help you to compute the above said value.

What is a Rectangle?

It is a quadrilateral, having four sides, whose corners are at 90◦ angle or right angles. In addition, each side is of the same length as the opposite side. It also comprise of adjacent unequal margins.

The two sides indicating length are the same, likewise, the two sides representing width are the same. A square is an exceptional case, as its all 4 sides are equal.

Our portal present many useful calculators like slope calculator & probability calculator which students can use to enhance their learning and productivity.

Rectangle Area formula

The rectangle area formula is expressed as:

A = l × w

where,

Length = l. and Width = w

It is measured in square units, such as square cm, square inch, square feet and square meter.

How to find Length & Width using Rectangle Area formula?

Assume a lawn to be demarcated by a boundary line of having a length of 40 meters and a width of 25 meters. How much space would be enclosed within the borderline?

Length = 40m

Width = 25m

Area = A = ?

A = 40m * 25m

A = 1,000 m2

We can also find the length or width by adjusting the formula as follows:

L = A/W

L= 1000/25

L = 40m

How to find the area of a Rectangle?

To find the surface area of a rectangle, we just need two things the length and width of the two-dimensional shape. In a quadrilateral, the length usually refers to the extensive or longer of the two boundaries, while the width is represented by the shorter of the two sides.

How to find the area of a rectangle?

Above image has four sides of 90◦ angle and all sides are not equal. The lengthier sides AB and CD represents the length, where AB is denoted by letter a. The shorter edges are AC and BD indicating the width, where AC is denoted by letter b. To get this space, we multiply the sides a × b.
