Answer:
Step-by-step explanation: you answered the question
1 yard=3 feet
4yards= 4•3= 12 feet
Perimeter of a square = 4•side = 12 so side of the square is 3 feet
Area of square = 3•3=9 Square feet
Answer: 7
Step-by-step explanation:
just use a comparison
3/12 = x/28
1/4 = x/28
x = 7
Let y directly proportional to X
thus y = CX
where c is proportionality constant
given c= 9
thus y = 9x
