A small farm field is a square measuring 320 ft on a side. What is the perimeter of the field? If you double the length of each side of the field, what is the new perimeter?

old per: 1280

new per:2560

Step-by-step explanation:

first perimeter u get it by adding all the sides and since its a square  then all the sides are equal so u can just do

320*4 which is equal to 1280

and by doubling the sides u can just double it in the old equation meaning

(320*2)*4

which is equal to 2560

a) 320 times 4= 1280 ft

b) 320 times 2= 640 so 640 times 4= 2560ft
