Question

You are building a rectangular deck. The area of the deck should be 250ft². You want the length of the deck to be 5 ft longer than twice its width. What should the dimensions of the deck be?

Answer 1

I think the answer to this problem is the width is 10 and the length is 25 because of this of this equation 2w^2+5w-250=0
Then..
(2w+25)*(w-10)=0
and you get the answer of w=10 and l=25
