Question

the breadth of rectangle whose length is 12 cm and perimeter is 36cm is​

Answer 1

Here the perimeter and length of a triangle is given

Perimeter = 36 cm

Length = 12 cm

We have to find the breadth of the triangle

We will use the formula of the perimeter of a rectangle

Perimeter = 2 ( length + breadth )

Putting the values in the above formula

36 = 2 ( 12 + breadth )

18 = 12 + breadth

breadth = 18 - 12

breadth = 6

Hence, the breadth of the rectangle will  be 6 cm

Answer 2

To find : breadth of rectangle

Given : length = $12\ cm$  perimeter = $36\ cm$

Solution :

• According to question we are given that length is $12\ cm$ and perimeter is $36\ cm$.

• To find perimeter we use following formula -
• Perimeter of rectangle =  $2 ( l + b)$

• Substituting the values we get,

          $36 = 2 ( 12 + b ) \\36 = 24 + 2b \\b = \frac{12}{2} \\b = 6 \ cm$

Hence, breadth $6\ cm$ .
