Question

The $\underline{{}}\underline{{}}\underline{{}}\underline{{}}\underline{{}}$ of a figure is the total distance around the edge of the figure.
A. Area
B. Perimeter
C. Volume
D. Surface

Answer 1

Hint: We solve this question by using the basic mathematical definitions of what each of the given terms in the options mean. Then we select the right option and represent the answer by filling in the blanks.

Complete step by step solution:
In order to solve this question, let us consider the options one after the other. We explain what each of these terms mean and the best matching one is considered as the solution.
First let us consider the option A. Area of a geometrical figure means the region or space enclosed by a boundary. It is represented in square units. It is usually measured for two dimensional objects. For three dimensional objects it is known as surface area.
Next, we take option B which is perimeter. Perimeter represents the length of the boundary around the edge of the figure. It is also called the outline of the figure.
Third option given is volume which means the space enclosed by a three-dimensional object. It is represented in cubic units.
Fourth option surface means the outer region or layer of an object. This is represented by the region inside the boundary of the object.
Looking at the above options, we can clearly see that options A, C and D do not satisfy the question. The best fit for the blank is option B which is perimeter.

Hence, the $\underline{\text{perimeter}}$ of a figure is the total distance around the edge of the figure.

Note:
We need to know the basic mathematical terms and their definitions or what they mean. It is important to note that the above terms are not just for a specific object but can be for a variety of objects such as a circle, sphere, cylinder, etc. It is important to know their formulas too in order to solve many more mathematical problems.
