1) The length of a side of a square is equal to a length of a side of a heptagon. If the perimeter of the heptagon is 84cm, what is the area of the square?

2) Given that 2^x=7 and 2^y=38 find out what 2^(x+y) is .....(where ^ = power of)

I assume that since Timbo is correct, then so am I, since we both tendered the same answer! <img src=/S/grin.gif border=0 alt=grin width=15 height=15>
I further assume that you were querying my answer to 1.
