Question
Find the area of the following figures.
✓
Answer
(i)
∴ Total area of the figure = 3 + 1 = 4 sq. units
(ii)
∴ Total area of the figure = 6 + 3 = 9 sq. units
(iii)
∴ Total area of the figure = 7 + 3 = 10 sq. units
(iv)
∴ Total area of the figure = 8 + 3 = 11 sq. unit
| Covered Area | Number | Area Estimated (sq. units) |
| Fully-filled squares | 3 | $3 \times 1=3$ |
| Half-filled squares | 2 | 2 × $ \frac{1}{2} $ = 1 |
(ii)
| Covered Area | Number | Area Estimated (sq. units) |
| Fully-filled squares | 6 | $6 \times 1=6$ |
| Half-filled squares | 6 | 6 × $ \frac{1}{2} $ = 3 |
(iii)
| Covered Area | Number | Area Estimated (sq. units) |
| Fully-filled squares | 7 | $7 \times 1=7$ |
| Half-filled squares | 6 | 6 × $ \frac{1}{2} $ = 3 |
(iv)
| Covered Area | Number | Area Estimated (sq. units) |
| Fully-filled squares | 8 | $8 \times 1=8$ |
| Half-filled squares | 6 | 6 × $ \frac{1}{2} $ = 3 |
| More than half of a square | 0 |
