What is the Area of a Rectangle?

A rectangle is a 2-D (two-dimensional) geometrical figure having four sides. It has two pairs of opposite and parallel sides in a rectangle. The two sides of the rectangle are perpendicular to each other and meet at the right angles. Each interior angle of the rectangle is 90 degrees. The area of a rectangle is calculated with the help of its sides. The area of a rectangle is the product of the adjacent sides.

How to Find the Area of a Rectangle?

Those who want to know how to find the area of a rectangle must know the area of a rectangle formula.

The area of a rectangle formula is mentioned below.

A (Area of a rectangle)= Length (L) × Width (W)

Area of a Rectangle Examples

Students can glance through the given examples to understand how to calculate the area of a rectangle

Garden (Length = 20 m, Width = 15 m)

●     Formula: Area = Length × Width

●     Calculation: 20 × 15 = 300 m²

Book Cover (Length = 25 cm, Width = 18 cm)

●     Formula: Area = Length × Width

●     Calculation: 25 × 18 = 450 cm²

Football Field (Length = 100 m, Width = 50 m)

●     Formula: Area = Length × Width

●     Calculation: 100 × 50 = 5,000 m²

Swimming Pool (Length = 8 m, Width = 4 m)

●     Formula: Area = Length × Width

●     Calculation: 8 × 4 = 32 m²

FAQs

Q1: How is the area of a rectangle calculated?

A1: The area of a rectangle is calculated by multiplying the length of a rectangle with its width.

Q2: How to calculate the area of land with 4 unequal sides?

A2: To calculate the area of land with four unequal sides, follow these steps:

• Divide the land into two triangles with the help of a diagonal
• Apply the appropriate property of triangles to identify the type of triangle and calculate the length of sides of both triangles
• Find out the area of both triangles of the land
• Add the area of both triangles to get the required land area with four unequal sides

Q3: How do you find the area of a rectangle?

A3: To find the area of a rectangle, the length of the rectangle must be multiplied by the width of the rectangle.

Q4: What is the formula for the area of the rectangle?

A4: The area of a rectangle formula is:

A = L*B where,

A = Area, L = Length and B = Breadth.

If the mathematical problem includes the height and width of a rectangle, the area of rectangle formula will be: 

A = H*W (Where A = Area, H=Height and W=Width)

Q5: How to find the area and perimeter of a rectangle?

A5: To find the area of a rectangle, multiply its length with the breadth/width. The formula to calculate the perimeter of a rectangle is:

2 (L+B), where L stands for Length and B stands for Breadth.

Q6: How to find the perimeter of a rectangle with area?

A6: Calculating the perimeter of a rectangle with area is possible only when length or breadth is provided in the question. Calculate the length of the other side using either of the given formulas as per the question:

Length=Area/Breadth or Breadth=Area/Length

Once length and breadth are calculated, the formula of the perimeter of the rectangle (2(L+B) must be applied.

Q7: How do you calculate the surface area of a rectangle?

A7: The length of the rectangle is multiplied by its width (A=L*W) to calculate the surface area of a rectangle.
