Question

what is the perimeter of a rectangle give some examples​

Answer 1

Answer:

Perimeter of rectangle = 2(L+B)

Step-by-step explanation:

For example:

A rectangle has length 2cm and a breadth 3cm So it's perimeter will be

2(2+3) = 2(5) = 10 cm

Answer 2

Rectangles are four-sided polygons.

Following are the properties of a rectangle:

(i) All the angles of a rectangle are 90º.

(ii) Opposite sides of a rectangle are always the same in size.

Perimeter of a rectangle

The perimeter of a rectangle is the total length of all the sides of the rectangle. Hence, we can find the perimeter by adding all four sides of a rectangle.

$The \: formula \: for \: the \: perimeter \: of \: a \: rectangle = 2(l + b)$

where l is the length and b is the breadth.

For eg. Find the perimeter of a rectangle with length 4cm and breadth 2cm.

$2(l + b) = 2(4 + 2) \\ = 2 \times 6 \\ = 12$

hope this concept is clear for you..☺
