Question 41402: I have a hard time figuring word problems, can someone please help?
A garden area is 30 feet long and 20 feet wide. A path of uniform width is set around the edge. If the remaining garden area is 400 feet squared, what is the width of the path?
Answer by Paul(988) (Show Source): You can put this solution on YOUR website!
400=(30+2x)(20+2x)-(30*20)

Solve that and you get x=3.5 (rounded)
Hence, the uniform width is 3.5'
