Question

Is it possible to construct a rectangle whose length is 1cm less than twice its width, and whose area is 40cm^2? If your answer is yes, determine the dimensions of the rectangle to the nearest tenth of a centimetre. If your answer is no, explain why it is not possible.

I know it's possible, but I don't know how to get the answer. Please help me! My test is tomorrow. ><

Thanks!

Answer 1

I'm at a loss, so I put impossible rectangle in the search engine. A site called Stella's Stunner's may be able to help, good luck!
