Exercise – 10.2
1. Find the areas of the following figures:
Solutions :
(a)
| Cover | Number estimate | Area | |
| (i) | Full-filled squares | 9 | 9 x 1 = 9 sq units |
| (ii) | Half-filed squares | – | – |
| (iii) | More than half-filed squares | – | – |
| (iv) | Less than half-filed squares | – | – |
∴ Total area of the figure = 9 sq units
(b)
| Cover | Number estimate | Area | |
| (i) | Full-filled squares | 5 | 5 x 1 = 1 sq units |
| (ii) | Half-filed squares | – | – |
| (iii) | More than half-filed squares | – | – |
| (iv) | Less than half-filed squares | – | – |
∴ Total area of the figure = 5 sq units
(c)
| Cover | Number estimate | Area | |
| (i) | Full-filled squares | 2 | 2 x 1 = 2 sq units |
| (ii) | Half-filed squares | 4 | 4 x |
| (iii) | More than half-filed squares | – | – |
| (iv) | Less than half-filed squares | – | – |
∴ Total area = 2 sq units + 2 sq units = 4 sq units.
(d)
| Cover | Number estimate | Area | |
| (i) | Full-filled squares | 8 | 8 x 1 = 8 sq units |
| (ii) | Half-filed squares | – | – |
| (iii) | More than half-filed squares | – | – |
| (iv) | Less than half-filed squares | – | – |
∴ Total area of the figure = 8 sq units
(e)
| Cover | Number estimate | Area | |
| (i) | Full-filled squares | 10 | 10 x 1 = 10 sq units |
| (ii) | Half-filed squares | – | – |
| (iii) | More than half-filed squares | – | – |
| (iv) | Less than half-filed squares | – | – |
∴ Total area of the figure = 10 sq units
(f)
| Cover | Number estimate | Area | |
| (i) | Full-filled squares | 2 | 2 x 1 = 2 sq units |
| (ii) | Half-filed squares | 4 | 4 x |
| (iii) | More than half-filed squares | – | – |
| (iv) | Less than half-filed squares | – | – |
∴ Total area = 2 sq units + 2 sq units = 4 sq units.
(g)
| Cover | Number estimate | Area | |
| (i) | Full-filled squares | 4 | 4 x 1 = 4 sq units |
| (ii) | Half-filed squares | 4 | 4 x |
| (iii) | More than half-filed squares | – | – |
| (iv) | Less than half-filed squares | – | – |
∴ Total area = 4 sq units + 2 sq units =6 sq units.
(h)
| Cover | Number estimate | Area | |
| (i) | Full-filled squares | 5 | 5 x 1 = 5 sq units |
| (ii) | Half-filed squares | – | – |
| (iii) | More than half-filed squares | – | – |
| (iv) | Less than half-filed squares | – | – |
∴ Total area of the figure = 5 sq units.
(i)
| Cover | Number estimate | Area | |
| (i) | Full-filled squares | 9 | 9 x 1 = 9 sq units |
| (ii) | Half-filed squares | – | – |
| (iii) | More than half-filed squares | – | – |
| (iv) | Less than half-filed squares | – | – |
∴ Total area of the figure = 9 sq units.
(j)
| Cover | Number estimate | Area | |
| (i) | Full-filled squares | 2 | 2 x 1 = 2 sq units |
| (ii) | Half-filed squares | 4 | 4 x |
| (iii) | More than half-filed squares | – | – |
| (iv) | Less than half-filed squares | – | – |
∴ Total area = 2 sq units + 2 sq units = 4 sq units.
(k)
| Cover | Number estimate | Area | |
| (i) | Full-filled squares | 4 | 4 x 1 = 4 sq units |
| (ii) | Half-filed squares | 2 | 2 x |
| (iii) | More than half-filed squares | – | – |
| (iv) | Less than half-filed squares | – | – |
∴ Total area = 4 sq units + 1 sq units = 5 sq units.
(l)
| Cover | Number estimate | Area | |
| (i) | Full-filled squares | 2 | 2 × 1 = 2 sq units |
| (ii) | Half-filed squares | – | – |
| (iii) | More than half-filed squares | 6 | 6 × 1 = 6 sq units |
| (iv) | Less than half-filed squares | 6 | 6 × 0 = 0 sq units |
∴ Total area = 2 sq units + 6 sq units = 8 sq units.
(m)
| Cover | Number estimate | Area | |
| (i) | Full-filled squares | 5 | 5 × 1 = 5 sq units |
| (ii) | Half-filed squares | – | – |
| (iii) | More than half-filed squares | 9 | 9 × 1 = 9 sq units |
| (iv) | Less than half-filed squares | 12 | 12 x 0 = 0 sq units |
∴ Total Area = 5 sq units + 9 sq unit = 14 sq units
(n)
| Cover | Number estimate | Area | |
| (i) | Full-filled squares | 8 | 8 × 1 = 8 sq units |
| (ii) | Half-filed squares | – | – |
| (iii) | More than half-filed squares | 10 | 10 × 1 = 10 sq units |
| (iv) | Less than half-filed squares | 9 | 9 x 0 = 0 sq units |
∴ Total area = 8 sq units + 10 sq units = 18 sq units
