The number of square units required to cover a surface is called

• A. Area
• B. Perimeter
• C. Volume
• D. Circumference

Answer: (A)

Area is the amount of space inside a flat surface, measured in square units. The phrase “number of square units required to cover a surface” describes area because you can imagine tiling the shape with unit squares and counting how many fit. For example, a rectangle that's 3 units long and 4 units wide has an area of 12 square units. Perimeter is the distance around the edge of a figure, not how much surface it covers. Volume is the amount of space a solid object occupies in three dimensions. Circumference is the distance around a circle, a specific boundary length. So the term that matches the description is area.
