The number of unit squares that can fit into any form is its area. The term “unit” refers to one (1), therefore a unit square is a square having one (1) unit of side. As a result, the area of a rectangle is equal to the number of unit squares within the rectangle’s edge. The area of a rectangle, on the other hand, is the space occupied within the rectangle’s perimeter. The unit length tiles in your home are a fantastic illustration of a rectangular form. By counting the number of tiles on the floor, you can quickly determine how much area it takes up. This will also assist you in determining the rectangle floor’s area.
What is the Area of a Rectangle?
The area of a flat surface of a specific form may be described as the amount of space it covers. t’s computed as a “quantity” of square units (square centimeters, square inches, square feet, etc.) The area of a rectangle is the number of unit squares that can fit within it. Laptop screens, blackboards, painting canvas, and other rectangular shapes are examples of flat surfaces.
Area of a Rectangle Definition: Area occupied by a rectangle within its boundary is called the area of the rectangle.
Area of a Rectangle Formula
The area occupied by a rectangle within its boundaries is calculated using the area of a rectangle formula. The area of the rectangle with a length of 4 inches and a width of 3 inches in the example above is 12 square inches. 4 3 = 12 is the answer. A rectangle’s area is calculated by multiplying its length and breadth. As a result, the formula for the area, ‘A,’ of a rectangle with length and breadth of ‘l’ and ‘w,’ respectively, is “l x w.”
Area of a Rectangle = (Length × Breadth) square units
How to Calculate Area of Rectangle?
A rectangle’s area is equal to its length multiplied by its breadth. To find the area of a rectangle, follow the steps below:
Step 1: From the supplied data, take note of the length and width dimensions.
Step 2: Calculate the sum of the length and width values.
Step 3: Write your solution in square units.
Consider the following example to learn more about how to calculate the area of a rectangle.
. We’ll calculate the area of a rectangle with a length of 15 units and a width of 4 units. First, determine the length and breadth of the region.
Length = 15 units and breadth = 4 units.
A = lxw is the formula for calculating the area of a rectangle. In this formula, replace ‘l’ with 15 and ‘w’ with 4. This means that the rectangle’s area is 15×4 = 60.
As a result, the rectangle’s area is 60 square units.
Area of a Rectangle by Diagonal
The diagonal of a rectangle is the straight line that connects the opposing vertices of the rectangle. In the rectangle, there are two diagonals, each of equal length. The Pythagoras theorem may be used to calculate the diagonal of a rectangle..
(Diagonal)2 = (Length)2 + (Breadth)2
(Length)2 = (Diagonal)2 – (Breadth)2
Length = ⎷(Diagonal)2 – (Breadth)2
For a rectangle, the formula is Length × Breadth. Alternatively, we can write this formula as ⎷((Diagonal)2 – (Breadth)2) × Breadth.
So, Area of a Rectangle = Breadth (⎷(Diagonal)2 – (Breadth)2).
