Area of Rectangle Formula Class 7

The area of a rectangle is the total space covered by it. The formula for the area of a rectangle can be easily memorized if the underlying logic is understood well. This article presents a precise summary of the area of rectangle formula class 7 that will ensure that students understand the concept of calculating the area of rectangle and its application along with some effective tips to remember the area of rectangle formula for class 7.

List of Area of Rectangle Formula Class 7 

The following points present a summary of the concepts and formulas related to the area of a rectangle.

• The opposite sides of a rectangle run parallel to each other, while the adjacent sides stand perpendicular to each other. 
• Area of a rectangle is basically the multiplication of the measurements of its two adjacent sides. 
• Area of rectangle = Length × Breadth
• Since the calculation of area involves multiplication of two measurements, hence, a rectangle’s area is always represented in square units.
• The perimeter of a rectangle is the total length of all its sides.
• Perimeter of a rectangle = 2 × (Length + Breadth)

Applications of Area of Rectangle Formula Class 7

Rectangles are the most commonly used shapes around us. The two main dimensions of a rectangle are its area and the perimeter. The following examples show how these parameters have their applications in the real world.

• The ability to calculate a rectangle’s area simplifies numerous domestic tasks in everyday life. For example, to paint a rectangular wall, we need to calculate the area of the wall to determine how much paint is required. 
• For rectangular farms, farmers use the farm area to figure out how many seeds and manure they need.
• In order to build a house on a rectangular piece of land, the area of land is required to estimate the quantity of the raw material.

Tips to Memorize Area of Rectangle Formula Class 7

Sometimes memorizing formulas becomes difficult and students tend to forget them due to nervousness. The following points list a few tips to memorize these formulas easily.

• The students must try to solve all the solved examples in their textbooks as these examples are meant to cover all the important basic concepts. After completing the solved examples they can move on to the exercise questions. Consistent practice will help the students memorize the area of rectangle formula class 7 on their fingertips without any effort of mugging them up.
• Students must also download some formula images that can be found on the internet. They can use these as a screensaver on their digital gadgets. As a result, they will be reminded to glance at the formulas throughout the day anytime they use their device, resulting in a speedy revision.
• Studying with friends can also help the students in clearing out their doubts with each other. This will not only make learning easy and fun but will also result in sharing of ideas regarding solving problems that will help them in examinations.

Area of Rectangle Formula Class 7 Examples

Example 1: What is the area of a rectangular square park whose length and breadth are 40 m and 35 m respectively.

Solution: The area of a rectangle formula is given as Length × Breadth.

Substituting the given values we get, Area of the rectangular square park = 40 × 35 = 1400 m².

Example 2: If the area of a rectangle is 80 square units and its length is 10 units, what is its breadth? Also, find the perimeter of the rectangle.

Solution: We know the area of rectangle formula, Area of Rectangle = Length ×  breadth

Given, area of rectangle = 80 square units, Length = 10 units

Substituting the given values, we can find the breadth. 

Area of Rectangle = Length × breadth

80 = 10 ×  breadth

Breadth = 8 units

Now, we know the length and breadth of the rectangle so the perimeter of the rectangle can be easily calculated.

Perimeter of Rectangle = 2 (Length + Breadth) = 2 (10 + 8) = 2 × 18 = 36 unit²
