Question

a rectangle length is 12 cm perimeter 305 find breadth​

Answer 1

Answer:

hey Friend here is your answer

length = 12 cm

breadth = ?

perimeter of rectangle = 2( length + breadth)

305 = 2( 12 + ?)

305/2 = 12 + ?

305/2-12 = breadth

Answer 2

Answer:

Given :

Length of the rectangle = 12 cm.

Perimeter of the rectangle = 305 cm.

To find :

Breadth of the rectangle =?

Formula Used :

Perimeter of the rectangle = 2( length +breadth)

Step-by-step explanation :

It is Given that,

Perimeter of the rectangle = 305 cm.

As We know that,

Perimeter of the rectangle = 2(length + breadth)

Substituting the values in the above formula, we get,

305 = 2(12 + breadth)

305 = 24 + 2 breadth

2 breadth = 305 - 24

2breadth = 281

breadth = 281/2

breadth = 140.5 cm.

Therefore, Breadth of the rectangle = 140. 5 cm.

Additional information :

Perimeter of the rectangle = 2(length + breadth)

Area of Rectangle = length x breadth.

Diagonal of rectangle = √ l² + b²
