Question

Why The Perimeter Of Rectangle is 2(l+b)​

Answer 1

Answer:

Perimeter of Rectangle could be considered as one of the important formulae of the rectangle. It is the total distance covered by the rectangle around its outside. In Maths, you will come across many geometric shapes and sizes, which have an area, perimeter and even volume (for 3-d figures). You will also learn the formulas for all those parameters. Some of the examples of different shapes are circle, square, polygon, quadrilateral, etc. In this article, you will study the key feature of the rectangle, i.e. perimeter.

Answer 2

Answer:

Because it is the formula of perimeter of rectangle.

Step-by-step explanation:

For example:-

Length of a rectangle is 2cm and breadth is 5cm. We have to find its perimeter.

Let perimeter of the rectangle be x

x= 2(l+b)

x= 2(2+5)

x= 2(10)

x= 20

Therefore the perimeter of the rectangle is 20.
