Find the area of the region enclosed by the following figures by counting squares:

KnowledgeBoat · Accepted Answer

To estimate the area of a closed plane figure using a square paper, the following conventions are adopted: 1. The area of one complete square is taken as 1 sq. unit. 2. If more than half the square is covered by the region, then count it as 1 sq. unit. 3. If less than half the square is covered by the region, then ignore this portion. 4. If exactly half the square is covered by the region, then take its area as sq. unit. (i) By counting the unit squares enclosed by the figure: Number of complete covered squares = 9 Area of the region enclosed by the figure = 9 × 1 sq. unit = 9 sq. units Hence, the area of the region enclosed by figure (i) is 9 sq. units. (ii) By counting the unit squares enclosed by the figure: Area of the region enclosed by the figure = 5 sq. units Hence, the area of the region enclosed by figure (ii) is 5 sq. units. (iii) By counting the unit squares enclosed by the figure: Area of the region enclosed by the figure = 10 sq. units Hence, the area of the region enclosed by figure (iii) is 10 sq. units. (iv) By counting the unit squares enclosed by the figure: Area of the region enclosed by the figure = 6 sq. units Hence, the area of the region enclosed by figure (iv) is 6 sq. units. (v) By counting the unit squares enclosed by the figure: Area of the region enclosed by the figure = 4 sq. units Hence, the area of the region enclosed by figure (v) is 4 sq. units. (vi) By counting the unit squares enclosed by the figure: Area of the region enclosed by the figure = 6 sq. units Hence, the area of the region enclosed by figure (vi) is 6 sq. units.
