Answer:
Option B is the answer.
Step-by-step explanation:
The area of a surface can be measured in square meter (meter²).
Square meter means its a multiplication of two lengths measured in meter.
Option A.
m.cm = unit of length × unit of length
So we can measure the area by this unit.
Option B.
![\frac{ft^{3} }{m^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7Bft%5E%7B3%7D%20%7D%7Bm%5E%7B2%7D%20%7D)
Since ft³ is a unit of volume and m² of area. When we divide these units we get the unit of length.
Therefore, we can not measure the area by this unit.
Option C.
Inch² = unit of length × unit of length
So we can measure the area by this unit.
Option D.
m.ft = Unit of length × unit of length
Which shows its a unit of area.
Option E.
= ![\frac{\text{Unit of volume}}{\text{Unit of length}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BUnit%20of%20volume%7D%7D%7B%5Ctext%7BUnit%20of%20length%7D%7D)
= unit of area
Therefore, we can use this unit to measure the area.
Option B. is the answer.
