length l times width w = area A
Also we know that the length is 1cm more than 3 times the width.
Plugging that back into the Area equation, we get:
Two Real solutions!!
Because having a negative answer for a length doesn't make sense, we can disregard the -13/3 answer for w. So, width is 4. Length is 3 times width plus one, or 13.
- will leave that to the student to answer.
