Answer by josgarithmetic(39617) (Show Source): You can put this solution on YOUR website!
x and y dimensions;
xy=4200 and p for perimeter is p=2x+2y.

You only have enough information to make or ; or to solve each of these for y in terms of p or to solve x in terms of p. You need to know which variables are known and which variables are unknown.

Either py=8400+2y^2,
OR
px=2x^2+8400,
