Question

What do you understand by the quantity called ‘area’? 



A

It is the quantity of an object

loader
B

It is the length of an object

loader
C

It is the quantity that expresses the extent of a planar 2-D surface

loader
D

It is the height of an object

loader

Solution

The correct option is C

It is the quantity that expresses the extent of a planar 2-D surface


The first thing that needs to be understood is that area is a 2 dimensional quantity. Area is the quantity that expresses the extent of a two-dimensional figure or shape, or planar lamina, in the plane. It is only possible to measure area for 2-D surfaces. There is a different quantity to deal with areas for 3-D surfaces which we will look at slightly later in the upcoming questions.

Examples of 2-D surfaces are rectangles, circles, ellipse etc. It is possible to find area for all these 2-D surfaces. But area of objects such as cubes, cylinders, spheres etc. are not defined. But intuitively we know that there is some area associated with such 3-D objects. How come? The answer is coming soon!
