Question

a rectangular picture with a perimeter of 27 cm is glued in the center of a rectangular piece of cardboard. there is a 1 cm margin (of empty cardboard) all around the picture. what is the perimeter of the peice of cardboard

Answer 1

Answer:

31 cm

Step-by-step explanation:

A rectangle has 4 sides.

27 cm + 4 cm = 31 cm.

The perimeter is 31 cm.

If you are confused, to find perimeter you add all the sides up. That is why I added 1 + 1 + 1 + 1 / 4.

For inches or a different measure I recommend just converting it. You never mentioned the measure so I decided with cm.
