There are three species of the perch: Percaflavescens (Yellow perch), Perca fluviatilis(European perch) and Perca schrenkii (Balkhash perch).
There are many different kinds of perch. If you mean the perch that coarse fisherman catch in England, a predatory fish with a green striped body and red fins, then this is widely distributed through most waterways in the British Isles. There are also tropical perch species, that aren't related, such as the Ctenopoma or bush fish that live in Africa. And then there are many sea fish that are known as perch, that again aren't related, and which live all over the world.

It is very easy to tell the difference between a yellow perch and white perch. However, many people mistake white perch for silver bass. If you eat the fish you catch, there is a big difference in the taste of white perch and silver bass. White perch are very good; silver bass are a lot fishier tasting. The easiest way to tell the difference between a white perch and silver bass is by looking at their stripes on the side of the fish. White perch only have 1 solid stripe which is high up on their back. Silver bass, on the other hand, have five stripes on their sides and appear to be more silver in color. There are other differences between the two fish and hopefully in the future I can post a photo of a silver bass alongside a white perch and describe them to you.

True Yellow Perch (perca flavescens) originated in many areas of the Northern Hemisphere, especially in the Great Lakes region of the United States. That said, no fish name is more misused on restaurant menus than "perch". If in a restaurant, you see the word "perch" on a menu, and it is clarified as "Ocean Perch", "Rock Perch", "New England Perch", or "White Perch", it is a different, and almost invariably, inferior fish. Look for "Lake Perch", or "Yellow Lake Perch". That's the "Real McCoy".
It is impossible to answer as given as they measure different things: a square foot is a measure of AREA; whereas a perch is a measure of LENGTH. 1 perch = ¼ chain = ¼ × 66 ft = 16½ ft 1 sq perch = 1 perch × 1 perch = 16½ ft × 16½ ft = 272¼ sq ft → 1 sq ft = 4/1089 sq perch ≈ 0.00367 sq perch.
