i need lots of help its on big ideas math 6.4

Answer/Step-by-step explanation:
12 and 16 are your sides and since it says to go around then you are looking at perimiter.
So you need to add the sides up.
12*2=24 16*2=32 24+32=57
so it takes 57 miles to walk around the entire thing but you need to in in 4 minutes so divide it by 4.
57/4 = 14.25 per minute.
Answer/ Step-by-step explanation:
I found the very small mistake Wxlfie made:
12*2 = 24
16*2 = 32
24 + 32 = 56
56/4 = 14
The ant should walk 14 inches per minute.
Have a nice day! :)
