Explanation:

Step1: Calculate perimeter of part a

Count outer - side lengths. Each square has side length 1 unit. There are 16 outer - side lengths.
Perimeter = 16 units

Step2: Calculate area of part a

Count number of squares. There are 9 squares. Each square has area 1 square unit. Area = 9 square units

Step3: Calculate perimeter of part b

A parallelogram has two pairs of equal sides. Perimeter = 2×(7 + 5)=24 ft

Step4: Calculate area of part b

Area of parallelogram formula is A = base×height. Here, base = 7 ft and height = 4 ft. Area = 7×4 = 28 square ft

Step5: Calculate perimeter of part c

Perimeter of rectangle formula is P = 2×(l + w). Here, l = 15 cm and w = 8 cm. P = 2×(15 + 8)=46 cm

Step6: Calculate area of part c

Area of rectangle formula is A = l×w. A = 15×8 = 120 square cm

Answer:

a) Perimeter: 16 units, Area: 9 square units
b) Perimeter: 24 ft, Area: 28 square ft
c) Perimeter: 46 cm, Area: 120 square cm
