You are making a rectangular table. The area of the table should be 10ft squared. You want the length of the table to be 1ft shorter than twice its width. What should the dimensions of the able be?

**Steve**, Saturday, February 11, 2012 at 5:55pmas for the setup:

let the width be w

so, the length is 2w-1

area = w(2w-1) = 10

2w^2 - w - 10 = 0

(2w-5)(w+2) = 0

w = 2.5

so, 2w-1 = 4

the table is 2.5 x 4

Note that Kelli set it up so length = 2w+1
