### perimeter or area?

The problem states: You have made a quilt that is 4 t. by 5 ft. You want to use the remaining 10 square feet of fabric to add a decorative border of uniform width. What should the width of the border be?

Should I find the perimeter or the area of the quilt or do something else? I want to solve this problem today so would appreciate an answer as soon as possible.

Thank you.

draw a pic kind of like this: http://www.purplemath.com/modules/perimetr5.htm
(but dont cut out the corners)
the outside part is 2*(5+2x)(x)+2*(4)(x)=10
solve
