Let’s solve each rectangle and the square one by one.
We’ll use these formulas:
-
Perimeter of a rectangle = 2 × (length + width)
-
Area of a rectangle = length × width
- For a
square, all sides are equal, so:
- Perimeter = 4 × side
- Area = side × side

1) Rectangle: 10 m by 8 m
Perimeter = 2 × (10 + 8) = 2 × 18 =
36 m
Area = 10 × 8 =
80 m²
---
2) Rectangle: 9 in by 10 in
Perimeter = 2 × (9 + 10) = 2 × 19 =
38 in
Area = 9 × 10 =
90 in²
---
3) Rectangle: 13 in by 5 in
Perimeter = 2 × (13 + 5) = 2 × 18 =
36 in
Area = 13 × 5 =
65 in²
---
4) Rectangle: 13 in by 7 in
Perimeter = 2 × (13 + 7) = 2 × 20 =
40 in
Area = 13 × 7 =
91 in²
---
5) Rectangle: 9 ft by 5 ft
Perimeter = 2 × (9 + 5) = 2 × 14 =
28 ft
Area = 9 × 5 =
45 ft²
---
6) Rectangle: 5 in by 2 in
Perimeter = 2 × (5 + 2) = 2 × 7 =
14 in
Area = 5 × 2 =
10 in²
---
7) Rectangle: 11 ft by 5 ft
Perimeter = 2 × (11 + 5) = 2 × 16 =
32 ft
Area = 11 × 5 =
55 ft²
---
8) Rectangle: 16 in by 9 in
Perimeter = 2 × (16 + 9) = 2 × 25 =
50 in
Area = 16 × 9 =
144 in²
---
9) Square: 8 in on each side
Perimeter = 4 × 8 =
32 in
Area = 8 × 8 =
64 in²
---
Square at bottom: 7 m on each side
Perimeter = 4 × 7 =
28 m
Area = 7 × 7 =
49 m²
---
Final Answer:
1) Perimeter: 36 m, Area: 80 m²
2) Perimeter: 38 in, Area: 90 in²
3) Perimeter: 36 in, Area: 65 in²
4) Perimeter: 40 in, Area: 91 in²
5) Perimeter: 28 ft, Area: 45 ft²
6) Perimeter: 14 in, Area: 10 in²
7) Perimeter: 32 ft, Area: 55 ft²
8) Perimeter: 50 in, Area: 144 in²
9) Perimeter: 32 in, Area: 64 in²
Bottom square: Perimeter: 28 m, Area: 49 m²
