Answer:
1. 6 ft
2. 1 ft
3. 1/2 ft
Step-by-step explanation:
We know that the quilt is the shape of a square, since we are told that the main design has the same length sides of 5 ft.
Area of a square = s² (where s is the side length)
If the finished quilt has an area of 36 ft² then the length of one side is:
⇒ s = √(36) = 6 ft
Side length of main design = 5 ft
Side length of finished quilt = 6 ft
6 - 5 = 1 ft
Therefore, the border increased the total length of each side by 1 ft
As the border goes around the whole quilt, this means that the extra 1 ft needs to be divided by 2, so that each side has an equal amount added.
Therefore, the width of the border is 1/2 ft
