Explanation:
We need to find the
area and
perimeter of each rectangle.
For any rectangle:
-
Area = length × width
-
Perimeter = 2 × (length + width)
Make sure units match — we’ll keep them as given (ft, in, cm, m, yd, mm, km), and multiply accordingly.
Let’s go one by one:
---
1. 9 ft by 6 ft
Area = 9 × 6 =
54 ft²
Perimeter = 2 × (9 + 6) = 2 × 15 =
30 ft
2. 3 ft by 11 ft
Area = 3 × 11 =
33 ft²
Perimeter = 2 × (3 + 11) = 2 × 14 =
28 ft
3. 7 cm by 13 cm
Area = 7 × 13 =
91 cm²
Perimeter = 2 × (7 + 13) = 2 × 20 =
40 cm
4. 22 in by 19 in
Area = 22 × 19
Let’s compute: 20×19 = 380, 2×19 = 38 → 380 + 38 =
418 in²
Perimeter = 2 × (22 + 19) = 2 × 41 =
82 in
5. 16 m by 25 m
Area = 16 × 25 =
400 m² (since 16×100 = 1600, so 16×25 = 1600 ÷ 4 = 400)
Perimeter = 2 × (16 + 25) = 2 × 41 =
82 m
6. 10 yd by 2 yd
Area = 10 × 2 =
20 yd²
Perimeter = 2 × (10 + 2) = 2 × 12 =
24 yd
7. 1 mm by 6 mm
Area = 1 × 6 =
6 mm²
Perimeter = 2 × (1 + 6) = 2 × 7 =
14 mm
8. 21 km by 44 km
Area = 21 × 44
Break it down: 20×44 = 880, 1×44 = 44 → 880 + 44 =
924 km²
Perimeter = 2 × (21 + 44) = 2 × 65 =
130 km
Double-check all calculations — they’re correct.
Final Answer:
1. Area = 54 ft², Perimeter = 30 ft
2. Area = 33 ft², Perimeter = 28 ft
3. Area = 91 cm², Perimeter = 40 cm
4. Area = 418 in², Perimeter = 82 in
5. Area = 400 m², Perimeter = 82 m
6. Area = 20 yd², Perimeter = 24 yd
7. Area = 6 mm², Perimeter = 14 mm
8. Area = 924 km², Perimeter = 130 km
