# Need help with dimensions question

Question asked by: chrisowen

Asked on: 15 Feb 2011

7 x 4 is 28 and 5 x 4 is 20 so it becomes 28 x 20 as the new dimensions.

And basically from there the question is straightforward: add two of those together each to get the new perimeter and multiply to get the area.
