Question 1.

Find the area of the following figures by counting squares

Solution:

(a) Number of full squares = 9

āµ Area of 1 square = 1 sq. unit

ā“ Area of the portion covered by the figure = 9 Ć 1 sq. unit = 9 sq. units

(b) āµ Number of full squares = 5

ā“ Area of the figure = 5 Ć 1 sq. unit = 5 sq. units

(c) Number of full squares = 2

Half squares = 4

ā“ Area covered by the figure

(d) Number of full squares = 8

ā“ Area covered by the figure

= 8 Ć 1 sq. unit = 8 sq. units

(e) āµ Number of full squares = 10

ā“ Area covered by the figure

= 10 Ć 1 sq. unit = 10 sq. units

(f) āµ Number of full squares = 2

Half squares = 4

ā“ Area of the figure

= 2 sq. units + 2 sq. units

= 4 sq. units

(g) Number of full squares = 4

Half squares = 4

ā“ Area of the figure

(h) āµ Number of full squares = 5

ā“ Area of the figure

= 5 Ć 1 sq. unit = 5 sq. units

(i) āµ Number of full squares = 9

ā“ Area of the figure = 9 Ć 1 sq. unit = 9 sq. units

(j) āµ Number of full squares = 2

Half squares = 4

ā“ Area of figure

(k) āµ Number of full squares = 4

Half squares = 2

ā“ Area of the figure

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

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

(l) āµ Number of full squares = 4

More than half squares = 3

Half squares = 2

ā“ Area of the figure

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

(m) āµ Number of full squares = 6

More than half squares = 8

Half squares = 0

ā“ Area covered by the figure = (6 Ć 1) sq. unit + (8 Ć 1) sq. unit

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

(n) āµ Number of full squares = 9

More than half squares = 9

ā“ Area of the figure

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