Question

which term describes the number of square units contained in the interior of a polygon?
a. area
b. perimeter
c. width
d. height

Explanation:

• Option A: Area is defined as the number of square units that cover the interior of a polygon (or any two - dimensional figure). For example, the area of a rectangle is calculated as $A = length\times width$, and the result is in square units (like square centimeters, square meters, etc.).
• Option B: Perimeter is the total length of the boundary of a polygon. It is measured in linear units (like centimeters, meters), not square units. For example, the perimeter of a rectangle is $P = 2\times(length + width)$.
• Option C: Width is a linear measurement (a side - length dimension) of a two - dimensional figure, measured in linear units, not square units.
• Option D: Height is also a linear measurement (used in formulas for area, like the height of a triangle or parallelogram) and is measured in linear units, not square units.

Answer:

A. Area
