Mars is viewed as the red planet because of the large amounts of iron oxide on the surface
There are many places to find the facts about Mars's surface. These facts can be found online and in the local library.
One, just like earth, Pluto and uranus. But if you mean how many sq km of surface area mars has the answer is: 144,798,500 km2 (source: wikipedia)
Mars has many surface features such as craters and extinct volcanoes, but does not have any 'spots' consisting of large and long lived storm systems in it's atmosphere like those found on Jupiter.

Both the surface of the moon and Mars are rocky and heavily cratered, with large expanses of barren and dusty plains. However, Mars also has features like mountains, canyons, and volcanic regions that distinguish it from the moon's more uniform surface. Additionally, Mars has a thin atmosphere and evidence of past liquid water, while the moon does not have an atmosphere or surface water.
Mars Odyssey, an orbiter that arrived at Mars in 2001, detected water ice beneath the surface of Mars using its gamma-ray spectrometer. This discovery provided important insights into the geological history and potential habitability of the planet.
Rocks and The Mars Rovers are on the surface of the planet Mars.
