Question

Tom has a backyard that is 100ft. by 60 ft. He plans to install a rectangulr swimming pool bordered by a concrete walkway of uniform width. He wants the area of the pool to take up 1/2 of the area od the entire backyard. Determine the width of the walkway

Answer 1

yard area = 100*60 = 6000
pool area = 3000

now, if the pool has width x, length y, and the walkway is w wide, we have

(x+2w)(y+2w) = 3000

Unfortunately, that's where we have to pause. You could have a tiny pool with a wide border, or a large pool with a skinny border.

Sure there's not something you're missing?
