Question 1.

Find the area of the following figures by counting squares

Solution:

(a) Number of full squares = 9

∵ Area of 1 square = 1 sq. unit

∴ Area of the portion covered by the figure = 9 × 1 sq. unit = 9 sq. units

(b) ∵ Number of full squares = 5

∴ Area of the figure = 5 × 1 sq. unit = 5 sq. units

(c) Number of full squares = 2

Half squares = 4

∴ Area covered by the figure

(d) Number of full squares = 8

∴ Area covered by the figure

= 8 × 1 sq. unit = 8 sq. units

(e) ∵ Number of full squares = 10

∴ Area covered by the figure

= 10 × 1 sq. unit = 10 sq. units

(f) ∵ Number of full squares = 2

Half squares = 4

∴ Area of the figure

= 2 sq. units + 2 sq. units

= 4 sq. units

(g) Number of full squares = 4

Half squares = 4

∴ Area of the figure

(h) ∵ Number of full squares = 5

∴ Area of the figure

= 5 × 1 sq. unit = 5 sq. units

(i) ∵ Number of full squares = 9

∴ Area of the figure = 9 × 1 sq. unit = 9 sq. units

(j) ∵ Number of full squares = 2

Half squares = 4

∴ Area of figure

(k) ∵ Number of full squares = 4

Half squares = 2

∴ Area of the figure

= 4 × 1 sq. unit + \(\frac { 1 }{ 2 }\) × 2 sq. unit

= 4 sq. units + 1 sq. unit = 5 sq. units

(l) ∵ Number of full squares = 4

More than half squares = 3

Half squares = 2

∴ Area of the figure

= 4 sq. units + 3 sq. units + 2 sq. unit = 9 sq. units

(m) ∵ Number of full squares = 6

More than half squares = 8

Half squares = 0

∴ Area covered by the figure = (6 × 1) sq. unit + (8 × 1) sq. unit

= 6 sq. units + 8 sq. units = 14 sq. units

(n) ∵ Number of full squares = 9

More than half squares = 9

∴ Area of the figure

= (9 × 1) sq. unit + (9 × 1) sq. unit = 9 sq. units + 9 sq. units = 18 sq. units
