Answer:
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
37 and 1 / 4 = 37 * 6 = 74 * 3 = 222
