I'm a homeschooled student and this problem is the last on a test. I don't know what's not clicking in my brain but I just can't figure out a formula. Can someone please help?

A rectangle is 4 times as long as it is wide. A second rectangle is 5 centimeters longer and 2 centimeters wider than the first. The area of the second rectangle is 270 square centimeters greater than the first. What are the dimensions of the original rectangle?

I understand the first and second rectangles would look like this:

4w 4w+5

w [ ] w + 2 [ ]

but that's as far as I get! What would the formula look like?

Thanks in advance for any help!
