Joe has made a quilt that is 4 feet by 5 feet.
He wants to use the remaining 10 square feet as a decorative border of uniform width.
What should the width of the border be?
------------------------
Let the width of the border be "x" ft.
---------------------------
Perimeter of the quilt is 2(4+5) = 18 ft
--------------------------------------------
Equation:
area of the border = 10 sq ft.
(x ft)(18 ft) = 10 sq ft
---
18x = 10
x = 5/9 ft
