Question

The amount of surface enclosed by a closed plane figure is called its
A) Area
B) Perimeter
C) Volume
D) None of these

Answer 1

Hint:
Here we will use the concept of the amount of surface enclosed. Surface enclosed by a two dimensional or closed plane figure which is measured in square units and used to cover a plane shape.

Complete step by step solution:
It is given that the figure is a closed plane figure which is defined as the two dimensional figure which is lying on a single plane.
Line segments are used to form a figure which is also known as the edges of the figure. The points at which these edges meet are known as the vertices of the figure.
Figures are generally known as polygons and these polygons generally vary according to the number of the edges of the figure.
The amount of surface enclosed by a plane is generally known as the area of the figure. Area is an enclosed region inside the edges of the figure.
Hence, the amount of surface enclosed by a closed plane figure is called its Area.

So, option A is the correct answer.

Note:
We should know that perimeter is the total length of the outer boundary of a shape in two dimensional which is the sum of all the edges of the figure. Perimeter is measured in meters. Area is the amount of surface covered by a shape in two dimensional. Surface area is the sum of all the areas of the faces of an object or shape. Area and surface area is measured in square meters. Volume is the amount of space occupied by an object in three-dimensional space. Volume is measured in cubic meters.
