What is the perimeter of a rectangle that has a area of 35 in to the square root of 2

35 in to the square root of 2 ?

Do you mean 35 in^2

If so, that's the power 2, not to the √2

Anyway, that's not enough information. Even if you restrict the rectangle to integer dimensions, it could be

1x35 - perimeter=72
5x7 - perimeter=24
