(first rectangle: length 12 ft, width 4 ft)
area=
perimeter=
(second rectangle: length 8 cm, width 2 cm)
area=
perimeter=
(third rectangle: length 15 in, width 12 in)
area=
perimeter=
(fourth rectangle: length 4 ft, width 3 ft)
area=
perimeter=
(fifth rectangle: length 4 cm, width 11 cm)
area=
perimeter=
(sixth rectangle: length 22 in, width 10 in)
area=
perimeter=

Explanation:

Step1: Recall area formula

Area of rectangle: $A = l \times w$

Step2: Recall perimeter formula

Perimeter of rectangle: $P = 2(l + w)$

Rectangle 1 (12 ft, 4 ft)

Step1: Calculate area

$A = 12 \times 4 = 48$

Step2: Calculate perimeter

$P = 2(12 + 4) = 2 \times 16 = 32$

Rectangle 2 (6 cm, 3 cm)

Step1: Calculate area

$A = 6 \times 3 = 18$

Step2: Calculate perimeter

$P = 2(6 + 3) = 2 \times 9 = 18$

Rectangle 3 (15 in, 12 in)

Step1: Calculate area

$A = 15 \times 12 = 180$

Step2: Calculate perimeter

$P = 2(15 + 12) = 2 \times 27 = 54$

Rectangle 4 (4 ft, 3 ft)

Step1: Calculate area

$A = 4 \times 3 = 12$

Step2: Calculate perimeter

$P = 2(4 + 3) = 2 \times 7 = 14$

Rectangle 5 (40 mm, 10 mm)

Step1: Calculate area

$A = 40 \times 10 = 400$

Step2: Calculate perimeter

$P = 2(40 + 10) = 2 \times 50 = 100$

Rectangle 6 (22 in, 10 in)

Step1: Calculate area

$A = 22 \times 10 = 220$

Step2: Calculate perimeter

$P = 2(22 + 10) = 2 \times 32 = 64$

Answer:

1. Area = $48$ square feet, Perimeter = $32$ feet
2. Area = $18$ square centimeters, Perimeter = $18$ centimeters
3. Area = $180$ square inches, Perimeter = $54$ inches
4. Area = $12$ square feet, Perimeter = $14$ feet
5. Area = $400$ square millimeters, Perimeter = $100$ millimeters
6. Area = $220$ square inches, Perimeter = $64$ inches
