Find the dimensions of the rectangle with minimum perimeter if its area is 400 square meters. Find the least perimeter.

I know that a rectangle has two sides that are equal and two other sides that are equal but I am unsure about what type of equation to use. I thought maybe I would try guess and check but I would rather have an equation.

**jim**, Saturday, October 31, 2009 at 2:16pm"two sides that are equal and two other sides that are equal" is a good start. Call the length of one type of side x, and the other y.

Then the area is x * y

And the perimeter is 2x + 2y

Check this on a small 5 * 3 rectangle, to be sure you understand it.

We are told the area is 400. Does this give you enough to go further?
