Answer:
The answer to your question is 643 cm²
Step-by-step explanation:
Data
Rectangle
length = 36 cm
width = 18 cm
Triangle
base = 5 cm
height = 2 cm
Process
1.- Find the area of the triangle
Area = length x width
Area = 36 x 18
Area = 648 cm²
2.- Find the area of the triangle
Area = base x height/ 2
Area = 5 x 2 / 2
Area = 5 cm²
3.- Find the remaining area
Remaining area = rectangle's area - triangle's area
Remaining area = 648 - 5
Remaining area = 643 cm²
