Problema Solution
Regina has started making baby quilts to sell. The inside of each quilt will measure 4 feet by 5 feet and will be surrounded by a border of uniform width. She wants each quilt to have a total area (including the border) of 30 square feet. Write and solve an equation to find the width of the border.
Answer provided by our tutors
Let 'w' represent the border's width of the quilt, w>=0.
The total area of the quilt equals:
(4 + 2w)*(5 + 2w) = 30

........
w = 0.5 ft
We need to ignore the negative solution -5 since the width can not be negative.
The width of the border is 0.5 feet.
