To what extent are the fundamental principles of microeconomics (like law of demand, law of substitution, consumer surplus etc )are applicable to macroeconomics?
I'd say about all of them.

please anyone provide me the answer as soon as possible.
The fundamental principles of microeconomics, such as the law of demand, law of substitution, and consumer surplus, can indeed have applications in macroeconomics, although the extent of their applicability may vary.
1. Law of Demand: The law of demand states that as the price of a good or service increases, the quantity demanded decreases, and vice versa, holding all other factors constant. In macroeconomics, this principle can be seen in the aggregate demand (AD) curve, which shows the relationship between the overall price level and the level of real GDP demanded. As the price level rises, consumers tend to demand less, resulting in a downward sloping AD curve.
2. Law of Substitution: The law of substitution states that individuals will tend to substitute a good or service with a cheaper alternative if the price of the original good or service increases. In macroeconomics, this principle can be applied to the concept of price elasticity of demand. If the price of a particular good or service rises significantly, consumers may switch to substitutes, affecting the overall demand for that good or service in the economy.
3. Consumer Surplus: Consumer surplus measures the difference between what consumers are willing to pay for a product or service and what they actually pay. While the concept of consumer surplus is typically associated with microeconomic analysis, it can also have implications in macroeconomics. For example, when analyzing the welfare effects of changes in government policies or the overall economy, understanding changes in consumer surplus can provide insights into the overall well-being of consumers.
However, it is important to note that macroeconomics deals with the behavior and performance of an entire economy, whereas microeconomics focuses on individual households, firms, and markets. The complexities and interdependencies within the macroeconomic realm often introduce additional factors that are not considered in microeconomics, such as aggregate supply, fiscal and monetary policies, and overall economic institutions. Therefore, while microeconomic principles can provide a foundation for understanding certain aspects of macroeconomics, their direct applicability may be limited in some macroeconomic contexts.
