Question

the perimeter of rectangle is 46 cm the breadth of rectangle is 12 cm find its length​

Answer 1

Answer:

The length is 11 cm

Step-by-step explanation:

Perimeter = 46 cm

Breadth = 12cm

perimeter of rectangle  = 2 (length + breadth )

            46 = 2(length + 12)

          length  + 12 = 46/2

          length = 23 - 12

          length = 11

Answer 2

☆ Solution ☆

Given :-

• The perimeter of rectangle is 46 cm.

• The breadth of rectangle is 12 cm.

To Find :-

• The length of rectangle.

Step-by-Step-Explaination :-

Let,

• The length of the rectangle be l

Now,

As we know that :-

Perimeter of rectangle = 2 ( length + breadth )

Where,

• The perimeter of rectangle = 46 cm

• The breadth of rectangle = 12 cm

• The length of rectangle = l

Putting the respective value,

46 = 2 ( l + 12 )

46 = 2l + 24

46 - 24 = 2l

22 = 2l

l = 22/2

l = 11

Hence,

The length of the rectangle is 11 cm
