Question. 10

The amount of region enclosed by a plane closed figure is called its ________.

Answer:

The amount of region enclosed by a plane closed figure is called its area.

Detailed Answer with Explanation:

Step 1: A plane closed figure is a flat shape that starts and ends at the same point. Examples: triangle, square, circle.

Step 2: The region enclosed means all the space inside the boundary of the shape.

Step 3: The amount of this inside space is called its area.

Step 4 (units): We measure area in square units, like \(\text{cm}^2\) or \(\text{m}^2\). Each \(\text{cm}^2\) is a little square that is \(1\,\text{cm}\) long and \(1\,\text{cm}\) wide.

Step 5 (quick examples):

  • A small square covers less space → smaller area.
  • A big rectangle covers more space → larger area.

Note: Area is different from perimeter. Perimeter is the length around the shape, while area is the space inside it.
