Just to help you, that formula is saying that 1 mile is equivalent to 5280 feet, i.e. the number of feet is equal to 5280 * number of miles.
So, you know the number of feet = 21,120 and have to convert that into the equivalent number of miles:
f = 5280m => m = f / 5280
m = 21,120 / 5280 = 4 miles
Answer: 4 miles
Answer:
14.2 Units
Step-by-step explanation:
The second shape is given to confuse you and is not actually necessary.
To work out the perimeter of an irregular shape you simply add up the lengths of each side. The shape you have here is an irregular quadrilateral as it has four corners and no recognisable/coarrale organisation.
1.4units + 2.2units + 4.5units +6.1units = 14.2 units.
I hope this helps :)
