Answer:
78 cm²
42 cm
Step-by-step explanation:
To obtain the area of the shape given :
The figure is divide into three different rectanglular parts :
Recall, area of a rectangle = Length x width :
Rectangle 1 : 9* 6 = 54 cm²
Rectangle 2 = 6 * 2 = 12 cm²
Rectangle 3 = 4 * 3 = 12 cm²
Total area = (54 + 12 + 12). = 78 cm²
Perimeter = sun of the exterior sides of the shape
Perimeter = (9 + 8 + 3 + 4 + 3 + 6 + 3 + 6) = 42 cm
