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.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
