The circle.
Next comes the square.

A square that measures 4 per side. Perimeter = L + L + L + L = 4L = 4*4 = 16 Area = L * L = 4*4 = 16 Although technically they won't be equal since perimeter has units of length, while area has units of squared length.
Triangle-least area, circle- most area, per given perimeter . The circle would have an area of 154 square cm. the triangle could have an area of almost zero if it were a long, skinny triangle. An equilateral triangle would have an area approx 92.8 sq cm.
The surface area is 600 sq. inches. The formula for surface area of a cube is 6s^2 where s is the side length. The general surface area formula is 2B+Ph where B is the area of the base, P is the perimeter of the base and h is the height.
Several uses come to mind. For one, the perimeter of a building, multiplied by the wall height gives an estimate of how much paint, siding, sheathing plywood, etc. are needed to do some work. For things with a circular shape, say a small lake, you can tell the distance across the lake by walking the perimeter and dividing that distance by pi to get the diameter, i.e., distance . Doing the same kind of thing on a flag pole allows you to decide how long the screws must be to mount a flag pulley. Another is using the perimeter of something like a lawn or garden to estimate how much seed, fertilizer, or other material is needed when you know that it should be used as so much per acre/square yard/square foot or other area.
A rectangle has a perimeter of 28 inches. The length of one pair of sides is 8 inches per side. What is the length of each of the other sides? Six in.
