Question

Find the perimeter of the rectangle 1 m and 20 cm is length and 60 cm is breadth

Answer 1

Answer:

360 cm

Step-by-step explanation:

L = 1m 20cm = 120cm

B = 60cm

Perimeter of rectangle = 2(l+b) units

= 2(120+60)

= 2(180)

= 360cm

Hence, 360 is the answer.

Answer 2

Length = 1 m 20 cm

Breadth = 60 cm

First, we will convert 1 m 20 cm into cm

so, 1 m = 100 cm

1 m 20 cm = 100 cm + 20 cm

                 = 120 cm

We have to find the perimeter of the rectangle

Perimeter = 2 ( length + breadth )

                = 2 ( 120 + 60 )

               = 2 × 180

               = 360 cm

Hence, the perimeter of the rectangle will be 360 cm
