FAQs on RS Aggarwal Solutions Class 6 Chapter-21 Concept of Perimeter and Area (Ex 21A) Exercise 21.1
1. How Perimeter and Area have been Defined in (Ex 21A) Exercise 21.1 in Class 6 Chapter-21?
In chapter 21 of class 6, the students are going to learn the Concept of Perimeter and the Area of an equilateral triangle. The term perimeter is defined as the sum of all sides of a closed figure. An equilateral triangle is defined as a triangle that owns all 3 of its sides in equal length. The perimeter of an Equilateral triangle remains equal to 3 times the total length of the side of a triangle. This is how it is defined for class 6 students.
2. For which Shape Perimeter is measured in Class 6 Chapter-21 Concept of Perimeter and Area (Ex 21A) Exercise 21.1?
A number of shapes are covered in Class 6 Chapter-21 Concept of Perimeter and Area (Ex 21A) Exercise 21.1. The students work on the perimeter of square, triangle, rectangle, equilateral triangle, regular octagon, regular pentagon, regular decagon, area of the square, area of the rectangle, finding a circle's diameter, the circumference of a circle, and much more to cover. The students should keep in mind that all these subjects are interlinked to each other so they should focus on it from an initial level.
3. If the Breadth and Length of a Rectangle Field are measured in the 7: 4 ratio, then the Field Fencing Cost will be 3300 i.e. Rupees 25 per Meter. You need to find the Field Dimension.
Fencing total cost is Rs 3300
The fencing rate is Rs 25/m
Field perimeter will be = fencing rate total cost = (Rs 3300Rs 25/m)=330025 m=132 m
If the breadth and length of the rectangular field will be respectively 7x and 4x
Field perimeter is = 2(7x + 4x) = 22x
This has been given that the field perimeter is 132 m.
∴ 22x=132⇒x=132/22=6∴ field length = (7 × 6) m=42 m field breadth = (4 × 6) m=24 m
