Let's say the mural originally is 100 x 100 = 10000 sq ft

 new size will be   124 x 112 = 13888 sq ft           

 

13888/10000 = 1.3888 times bigger  ...or   38.88 percent bigger   ~~ 39 percent

Thanks EP :)

yes I was going to let the original area be 1 and the new are will be

 

1.24*1.12 = 1.3888

 

So it has increased by 39%

I just realized this is a repeat question - I have deleted the onther one.

Please do not do that Tony. It means your question may get much more attention than it needs and someone else will not get answered at all.

You can draw attention to you question by posting a second request for help with a link (copy and paste the address) to the first question.

The question should then be answered on the ORIGINAL thread.
