Re: Find the perimeter of the square

x must be root(33) - 7

Then P = 4(x+7)

Re: Find the perimeter of the square

If we know the square has area 33cm^2 then we don't need to know anything about the side length to determine its perimeter -- was the question intended to be 'find x'?

Re: Find the perimeter of the square

Well if one side is (x+7) and its a square, then the perimeter is that side times 4.

4(x+7)
