Answer:

perimeter =3200cm

Step-by-step explanation:

l=12m=1200cm

w=400cm

perimeter=2(w+l)

=2(1200+400)

=2(1600)

=3200cm

The perimeter of a rectangle in cm that has a length of 12 meters and a width of 400cm is 3200 cm

perimeter of a rectangle = 2(l + w)

where

l = length

w = width

Therefore,

let's convert meters to centimetres

1m = 100 cm

12m = ?

cross multiply

length = 1200 cm

width = 400 cm

perimeter of the rectangle = 2(1200 + 400)

perimeter of the rectangle = 2(1600)

perimeter of the rectangle = 3200 cm
