a.

The most common unit used to measure the area of a sheet of paper is kilogram (kg), as the area depends on the weight of the sheet.

b.

The most common unit used to measure the area of a sheet of paper is liter (L), as the area depends on the amount of ink used in printing.

c.

The most common unit used to measure the area of a sheet of paper is degree Celsius (°C), as the area depends on the ambient temperature.

d.

The most common unit used to measure the area of a sheet of paper is cubic meter (m³), as the area is measured in three dimensions.

e.

The most common unit used to measure the area of a sheet of paper is square meter (m²), but it is common to use smaller units such as square centimeter (cm²) or square millimeter (mm²). To calculate the area of a sheet of paper, you just need to multiply the length by the width.
