A farmer is painting a new barn. He will need to calculate the surface area of the barn to purchase the correct amount of paint. In which of the following units can the farmer expect to calculate the surface area?

m
m2
ft
ft3

Area is written as square units, which is written as the units raised to the 2nd power.

The answer would be m^2

Answer : The farmer expect to calculate the surface area in unit is, m²

Step-by-step explanation :

In order to express a measurement there are many units that are used. It is International system of units known as S.I system, which is the scientific method that expresses the magnitude of basic units.

The S.I units are divided into two groups i.e. base units and derived units.

S.I base units are the units which are considered as the building blocks of system. The other units are derived from the S.I base units.

Derived units are the units which are derived from the base units by applying different operations in base units.

As we know that area is a type of derived unit because it is based on length or side. And area is the square of side.

The power of cube represent the unit of volume.

Thus, the farmer expect to calculate the surface area in unit is, m²
