Can someone help me?! The picture is below you don’t have to explain if you don’t want to!!

(a) 3:4

(b) 3:4

(c) 9:16

Step-by-step explanation:

(a) The ratio of the sides would be 15:20 but after you simplify them (divide by 5), you'd get 3:4

(b) The ratio of the perimeter would be 60:80 because you're multiplying each side length by 4. When you simplify this again (divide by 20), however, it becomes 3:4 again

(c) To find the area, you would multiply the width times height, the ratio would be 225:400. You would get the greatest common factor which is 25 and divide it on both sides to get 9:16

15.36 per mile

but forgot to round

i am pretty sure

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
