The Wire - Areas of a Square & Circle Along a Wire?

Hey guys, if there's any way one of you could point me in the right direction for this problem, I would greatly appreciate it.

A wire 360 inches long is cut into two pieces. One piece is formed into a square and the other into a circle. If the resulting square circle have the same area, find the lengths of the two pieces of wire to the nearest tenth of an inch.

Thanks in advance!

You can set up an equation that equates the two areas based on the length of their perimeters. For a square if the perimeter is x then one side is length x/4, and the area is (x/4)^2. For a circle if the circumference is y then the radius is y/(2 pi) and the area is y^2/(4 pi). Set these two areas equal, and add in the condition that x + y = 360, and solve for x and y.
