Explanation:

Rectangle 1 (12 ft × 4 ft)

Step1: Calculate area (length×width)

$\text{Area} = 12 \times 4 = 48$ square feet

Step2: Calculate perimeter (2×(length+width))

$\text{Perimeter} = 2 \times (12 + 4) = 32$ feet

Rectangle 2 (8 cm × 2 cm)

Step1: Calculate area (length×width)

$\text{Area} = 8 \times 2 = 16$ square centimeters

Step2: Calculate perimeter (2×(length+width))

$\text{Perimeter} = 2 \times (8 + 2) = 20$ centimeters

Rectangle 3 (15 in × 12 in)

Step1: Calculate area (length×width)

$\text{Area} = 15 \times 12 = 180$ square inches

Step2: Calculate perimeter (2×(length+width))

$\text{Perimeter} = 2 \times (15 + 12) = 54$ inches

Rectangle 4 (4 ft × 3 ft)

Step1: Calculate area (length×width)

$\text{Area} = 4 \times 3 = 12$ square feet

Step2: Calculate perimeter (2×(length+width))

$\text{Perimeter} = 2 \times (4 + 3) = 14$ feet

Rectangle 5 (4 mm × 11 mm)

Step1: Calculate area (length×width)

$\text{Area} = 4 \times 11 = 44$ square millimeters

Step2: Calculate perimeter (2×(length+width))

$\text{Perimeter} = 2 \times (4 + 11) = 30$ millimeters

Rectangle 6 (22 in × 10 in)

Step1: Calculate area (length×width)

$\text{Area} = 22 \times 10 = 220$ square inches

Step2: Calculate perimeter (2×(length+width))

$\text{Perimeter} = 2 \times (22 + 10) = 64$ inches

Answer:

1. Rectangle (12 ft × 4 ft): Area = 48 square feet, Perimeter = 32 feet
2. Rectangle (8 cm × 2 cm): Area = 16 square centimeters, Perimeter = 20 centimeters
3. Rectangle (15 in × 12 in): Area = 180 square inches, Perimeter = 54 inches
4. Rectangle (4 ft × 3 ft): Area = 12 square feet, Perimeter = 14 feet
5. Rectangle (4 mm × 11 mm): Area = 44 square millimeters, Perimeter = 30 millimeters
6. Rectangle (22 in × 10 in): Area = 220 square inches, Perimeter = 64 inches
