There are 5280 feet in a mile.
So to add fractions they need to have a common denominator, which in this case is 24. then multiply 1 by 4 and 5 by 3 because whatever you multiply the denominator by you need to do the same to the numerator, which will get you 4/24+15/24 then you add across the numerators and you get 19/24
Perimeter = length + length + width + width.
7y-7.5 + 7y-7.5 + 7.5y+8 + 7.5y +8
Combine like terms:
29y+1
The perimeter is 29y + 1 feet
1)b
2)a
