Question 4
In a 100 side square park has 5 m wide path inside it bound. Find out the area of path. Calculate the expenditure @ ₹250/- per 10 m² of cementing it.

Answer 1

Step-by-step explanation:

Side of the square ABCD = 100 m

width of the path = 5 m

side of the square EFGH = 90 m

area of ABCD = 1002 = 10000 m2

area of EFGH = 902 = 8100 m2

area of path = area of ABCD - area of EFGH = 10000 - 8100 = 1900 m2

cost of cementing 10 m2 = Rs. 250

cost of cementing 1900 m2 = Rs. Rs. 47500
