Algebraic Identity:
Difference of two squares : a² - b² = (a + b) ( a - b)
Square paddy field
Length = 48 m
Area = Length²
Area = 48² m²
Paddy field with the path:
Length = 52 m
Area = Length²
Area = 52² m²
Find the area of the pathway:
Area of the pathway = Difference of the two area
Area of the pathway = 52²- 48²
Applying the algebraic Identify:
Area of the pathway = (52 + 48) (52 - 48)
Area of the pathway = (100) (4)
Area of the pathway = 400 m²
Answer: The area of the pathway is 400 m²
