3 m
30 m
3 cm
30 cm
​

Answer 1

Answer:

Step-by-step explanation:

2 cm

Answer 2

Here the breadth and perimeter of a rectangle is given

Breadth = 20 cm

perimeter = 1 m

                 = 100 cm

We have to find the length of the rectangle

The formula of perimeter of rectangle is

Perimeter =  2 ( length + breadth )

           100 = 2 ( length + 20 )

               50 = length + 20

         length = 50 - 20

                     = 30 cm

Hence, the length of the rectangle will be 30 cm
