Question

The pathway of a square paddy field has 5 m width and length of its side is 40 m. Find
the total area of its pathway. (Note: Use suitable identity)​

Answer 1

The total area of the pathway is 700 sq m. This can be calculated as follows:

• We know that,

        Length of the square paddy field = 40 m

        Width of the pathway = 5 m

• Now, the Length of the pathway can be calculated as-

        = Length of the square paddy field - 2(width of the pathway)

        = 40 - 2(5)

        = 30 m

• Thus, the total area of the pathway is,

        = (40)² - (30)²

        = 1600 - 900

        = 700 sq m
