A rectangular piece of wood has a perimeter of 18 meters. If we multiply both its length and its width by 4, what will be the perimeter of the new enlarged piece of wood?
A. 36 m
B. 48 m
C. 64 m
D. 72 m
To find the answer, you need to know what the original perimeter is. Say the perimeter is 6+6+3+3. You multiply all of those numbers and you get 24+24+12+12. Add those together and you get 72.
