Thereof, what is the unit of an area?

In the International System of **Units** (SI), the standard **unit** of **area** is the square metre (written as m^{2}), which is the **area** of a square whose sides are one metre long. A shape with an **area** of three square metres would have the same **area** as three such squares.

Secondly, what is the unit of mass? The standard International System of Units (SI) unit of mass is the **kilogram** (**kg**). The **kilogram** is 1000 grams (g), first defined in 1795 as one cubic decimeter of water at the melting point of ice.

Likewise, people ask, how do you find the area?

To find the **area** of a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the **area**.

What is the unit for area of a circle?

Because the radius of a circle is equal to half its diameter, these equations are essentially the same. The units for area can be any unit for the measure of **length** squared: **feet** squared (**ft**^{2}), **meters squared** (**m**^{2}), **centimeters** squared (**cm**^{2}), etc.
