Answer:
First side: 12 feet, second side: 16 feet
Step-by-step explanation:
We know that the second side is 4 feet longer than the first side. If the first side is x, then the second side is x+4
b) The total amount of the border is 28 feet, so we can say that first side+second side=28, or
x+(x+4)=28
2x+4=28
2x=24
x=12 feet is the first side
x+4 = 16 feet is the second side
We can check that 12 feet + 16 feet = 28 feet as stated by the problem
