About 198 million square miles. The radius of Earth at the equator is about 3963 miles. The surface area of a sphere is given by Area = 4 pi r2, so the surface of the earth is: 4 x 3.14159 x 3963 miles x 3963 miles = 197,359,320.78684 square miles, plus a little extra to compensate for the vertical height of mountains and depth of valleys.
200,000,000 million (two hundred million) square miles.
If we approximate the earth as a smooth sphere with a radius of 3,959 miles,
then its surface area is 1.9696 x 108 square miles. (rounded)
"Two hundred million" is an easy way to remember it.
The Earth has a surface area of 196,939,900 square miles.
The surface area of the Earth is 510,072,000 km2 or 196,939.900 miles2
29.2 % (148,940,000 km²) is land
70.8 % (361,132,000 km²) is water

Mars has a diameter of 4,222 miles but from pole to pole, the diameter is 4,196 miles. Mars bulges at the equator, just like Earth.
Mars' total surface area is equal to 144,798,500 km² (55,907,000 square miles). This is about 28.4 percent of the Earth's total surface area.144,798,500 km2 or roughly one third the surface area of the Earth.
Venus is roughly the same size as Earth. Mars is only half the diameter of Earth and has less than 11% of the mass, and 28.4% of the surface area.
Earth is about 1.88 times larger than Mars.
Mars' diameter is about half that of the Earth and it's mass is only 10% of the Earth's.The total surface area of Mars is about the same as the total land area of the Earth.
