Question

The perimeter of a rectangle is 100 cm and its length is 30 cm . what is the breadth of the rectangle ? what is the area of the rectangle?

Answer 1

Perimeter of rectangle = 2(length + breadth)
----------------------------------

100= 2(30+ breadth)

100/2 = 30+ breadth

50=30 + breadth

50-30= breadth

20cm = breadth


-----------------------------------

Then,

Area of rectangle =length×breadth

Area of rectangle = 30×20

Area of rectangle = 600 cm²


I hope this will help you

Hello friends!!

☺️☺️ Here is your answer :

Perimeter of rectangle = 100 cm

Length l of rectangle = 30 cm

We have to find breadth of rectangle.

Let the breadth be b

We know that,

Perimeter of rectangle = 2 ( length + breadth )

100 = 2 ( 30 + b )

$\frac{100}{2} = 30 + b$

$50 = 30 + b$


$b = 50 - 30$


$b = 20$



Therefore , breadth of rectangle = 20 cm


Area of rectangle = length × breadth

= 30 × 20

= 600 cm²
