The following figures are drawn on a sheet of squared paper. Count the number of squares enclosed by each figure and find its area, taking the area of each square as 1 cm2.

1. Solution This figure contains 12 complete squares

Area of 1 small square = 1 cm2

Area of the figure = Number of complete squares × Area of the square

= (12 × 1) sq cm

= 12 sq cm

2. Solution This figure contains 18 complete squares

Area of 1 small square = 1 cm2

Area of the figure = Number of complete square × Area of the square

= (18 × 1) sq cm

= 18 sq cm

3. Solution This figure contains 14 complete square and 1 half square

Area of 1 small square = 1 cm2

Area of the figure = Number of complete square × Area of the square

= (14 × 1) + (1 × 1 / 2)

= 14 + 1 / 2

= 14 (1 / 2) sq cm

4. Solution This figure contains 6 complete squares and 4 half squares

Area of 1 small square = 1 cm2

Area of the figure = Number of complete squares × Area of the square

= (6 × 1) + (4 × 1 / 2)

= 6 + 4 / 2

= 16 / 2 {taking LCM}

= 8 sq cm

5. Solution This figure contains 9 complete squares and 6 half squares

Area of 1 small square = 1 cm2

Area of the figure = Number of complete squares × Area of the square

= (9 × 1) + (6 × 1 / 2)

= 9 + 6 / 2

= 24 / 2 {taking LCM}

= 12 sq cm
